Having Unity-like shortcuts for activating the first nine applications
in the dash has been a long requested feature, but somehow nobody got
around to implement it.
As the shortcut is most useful outside the overview where the dash is
not visible, only consider favorite apps as they have a predictable
order.

The `GetWindows` method gives access to the list of windows for each
application with some of their properties, so utilities such as dogtail
can pick the window of their choice to interfere with using the provided
window id.

Add a D-Bus API that allows the API user to introspect the application
state of the shell. Currently the only exposed information is list of
running applications and which one is active (i.e. has focus).
https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/326
Commit dbf993300a moved all inline D-Bus interface descriptions to template
strings so we can stop escaping line breaks.
Unfortunately that unveiled a grave bug in xgettext, which currently cannot
handle files that contain both backtick and slash characters - as a result,
translations from affected files have started to disappear as translators
run xgettext/msgmerge.
Instead of reverting the change and getting the crusty escaping back, we
will take this as an opportunity to stop inlining the XML altogether and
load it from a resource instead.
To facilitate that, add a small helper method that loads a D-Bus interface
description from a dedicated resource bundle.
https://gitlab.gnome.org/GNOME/gnome-shell/issues/537
We'll soon move the inlined XML of all interfaces we export or consume into
separate files. That's a significant increase from the interfaces for which
we install documentation, so it makes sense to use a dedicated subdir.

Reported by desktop-file-validate:
error: value "True" for boolean key "NoDisplay" in group "Desktop
Entry" contains invalid characters, boolean values must be "false" or
"true"
While the new per-desktop overrides in GIO are easier to use for
both developers and users, it is still inconvenient for everyone
who changed the defaults using the old overrides hack to lose
their settings. Address this by running a small script on startup
that migrates existing settings.
https://bugzilla.gnome.org/show_bug.cgi?id=786496
GSettings now recognizes per-desktop overrides that can be used
to change schemas' default values for a particular desktop. This
is not entirely unlike our existing custom override mechanism in
mutter, except that it is not limited to keys in org.gnome.mutter,
and it doesn't require a separate schema - the latter means that
we (and gnome-teak-tool) no longer have to figure out the correct
schema for the current login session and just use the original one.

We can simply request the symbolic variant from CSS so that we don't

Make the indicator for active remote access use the warning color, to

There are three units:

gnome-settings-daemon will use these, for example.

In places where numbers appear in columns (like the calendar widget) or

After the move to Gitlab, the gnome-shell-sass repository is more

* Remove tiny padding of user-list
* Less space between avatar and username
* Apply the 1em padding only to the user-widget, not the timed-login-indicator
Adjust the previous commit which applied the alignment to :first-child

The previous implementation of the CSS generation logic considered sassc
an optional dependency and made sure for that reason that the result CSS
files ended up in the source directory, so that they could be checked
in and kept in sync with the source sass files.
As we are making sassc a required dependency, we can now stop doing that
extra work and simply rely on the CSS files being automatically generated
each time the sass sources change. By doing this, we can now effectively
get rid of the CSS files checked in the repo as well as of the parse_sass.sh
script, since the CSS files will now live on the build directory only.
https://bugzilla.gnome.org/show_bug.cgi?id=792822
As the style has grown bigger and more complex, generating the different
variants from a common source has been a good decision. However given how
intertwined the theme is with gnome-shell itself, relying on a submodule
has proven to be quite painful. And as things stand right now, it is going
to get worse:
- using either pre-generated CSS or generating it at build time is
odd, and violates meson's strict separation between source- and
build directories; we are therefore considering dropping the CSS
and depending on sassc to always generate it at build time
- with the migration to gitlab, our workflow shifts decisively towards
branches; however there is no support in either git or gitlab for
handling two brances of separate repositories consecutively, which
gets particularly awkward for branches in a private namespace
With those pain points in mind, we will adjust our setup as follows:
- remove the submodule from gnome-shell and instead import the
sass as subtree
- after that, the sass sources can be changed like any other files
in the repository, and regular contributors can forget that there
was ever anything special about them
- whenever we want to update the classic style, we can push the subtree
changes and bump gnome-shell-extension's sass submodule
In other words: Updating the classic styling will become slightly more
painful, but not much and only for me; in return, everyone else can
stop fiddling with submodules (and buy me a beer).
All section titles use an icon, while all corresponding submenu items
are plain-text. As a result, labels in submenus aren't aligned with
the labels in the parent, which makes them harder to read and look
unbalanced. Address this by adding additional whitespace to submenu
items to account for the additional elements in the title.

When dragging a window between two workspaces a light effect used
to be present. The effect was lost probably during the theme revamp
in version 3.16.
https://bugzilla.gnome.org/show_bug.cgi?id=789103
As notification icons now align with the title, it makes sense for
them to follow the text size in case a text-scaling-factor other
than 1 is applied.
https://bugzilla.gnome.org/show_bug.cgi?id=788265
Using a unicode character here means it may look quite different
from the intended style (for instance with emoji fonts). Avoid
this by providing a custom icon and use that instead.
https://bugzilla.gnome.org/show_bug.cgi?id=766368
The legacy tray introduced as part of the notification redesign in
3.16 was meant as a stop-gap solution to encourage applications to
move away from the concept of status icons, but it hasn't really
done anything except of getting in the way. Given that the large
majority of apps that still make use of status icons work perfectly
fine without them, we decided that it is time to drop this unloved
bit of UI altogether. Users who still want them (or use one of the
odd cases where an app really depends on the icon) can install one of
various extensions that are available, either based on the XEmbed
support that is still kept around or implementing the DBus-based
StatusNotifier spec.
https://bugzilla.gnome.org/show_bug.cgi?id=785956
While the new title position gives the previews more space, they now
overlay the content which may hide valuable information. Address this
by only revealing the title as additional information on hover, like
we do for other auxiliary elements.
https://bugzilla.gnome.org/show_bug.cgi?id=783953
With the window titles no longer being shown as part of the previews
grid, we can reduce the spacing to have more space available to the
window previews themselves.
https://bugzilla.gnome.org/show_bug.cgi?id=783953
We consider the window previews the primary way to identify a window,
so it makes sense to give them as much space as possible. So in order
to not have title captions take up too much vertical space, overlay
them on top of the preview borders.
https://bugzilla.gnome.org/show_bug.cgi?id=783953
Meson is on track to replace autotools as the build system of choice,

Those will go away when we port authentication prompts to the new

A lot of our modal dialogs share a similar structure:
[Icon] Some title
Maybe a subtitle
And sometimes even a body for stuff like
longer descriptions.
A dedicated widget with a common style will allow us to significantly
reduce duplication of both code and CSS.

There is a clear difference between the file name and its associated
description which the mockups clearly highlight. Consequently,
make the description label semitransparent, in order to emphasize
the file name, not the description itself.
https://bugzilla.gnome.org/show_bug.cgi?id=749957
The current size of the text is way bigger than what
we want now. The default front size is what we are
looking after, therefore no explicit value is needed
to specify the font size.
https://bugzilla.gnome.org/show_bug.cgi?id=749957
The current separator uses a gradient effect as a separator
between search results. As the mockups suggest, the gradient
separator is no longer needed, in favor of a more simple one,
which is a thin semitransparent line.
https://bugzilla.gnome.org/show_bug.cgi?id=749957
In order to match the current mockups, the providerIcon
class needed to include both the name of the provider
and the label that informs the user about how many more
search results are available for that specific provider.
The latter replaces the plus sign icon that has been
used so far.
https://bugzilla.gnome.org/show_bug.cgi?id=749957
In order to make gnome-shell search functionality fit on
smaller screens, like those of devices, search results
need to take advantage of more horizontal space so that
any extra space can be used efficiently.
In order to do so, change the layout of the ListSearchResult
class from a vertical one, to a horizontal one and also
decrease the padding of the list-search-result-content css
class.
https://bugzilla.gnome.org/show_bug.cgi?id=749957
The user list uses the same indication for hover and focus, so it
is possible for two items to be highlighted at the same time. Using
different styling would improve the situation, but only to some
extent - the user would still need to figure out which highlight
corresponds to which activation method. So instead, copy the
approach we use in popup menus and use a single property for
highlights that is updated by both focus- and hover changes.
https://bugzilla.gnome.org/show_bug.cgi?id=772284
GTK+ switched from ruby-based sass to c-based sassc for performance

The solid black top bar we currently use works well for maximized
or tiled windows, as it puts focus on the application content by
blending into the monitor bezel. However it also visually reduces
the screen space, which is particularly noticeable when no window
is located nearby. Having the top bar blend with the background is
a better option in that case, so track window positions and add
some transparency when the top bar is free-floating.
https://bugzilla.gnome.org/show_bug.cgi?id=747163
The usual expectation when selecting large fonts is for content to
be bigger, not that less content is displayed. While not always
possible, there's no reason not to scale modal dialogues with the

Media notifications currently always show the forward and backward
buttons as clickable, regardless of whether the corresponding action
is available or not. Media players usually address this by rendering

Update the notification style according to the latest mockups:

The section titles usually don't provide a lot of value - messages
themselves are usually pretty unambiguous about their type, and
having a hidden shortcut to some settings panel or application isn't
essential either - except when showing the selected date when browsing
other days, as it adds context to the listed events. Based on that,
remove the section title as a general MessageListSection feature and
move it into the EventsSection, where we only show it when it is useful.
https://bugzilla.gnome.org/show_bug.cgi?id=775763
We will eventually remove section titles from the message list to
reduce visual noise and give the actual information provided by
the messages more space. So in order to not lose the ability to
mass-dismiss messages, the latest mockups spot a "Clear All" button
at the bottom - implement that.

Similar to the Clocks integration we've had in the date+time drop-down for

When gnome-shell fails to start on login, gnome-session tries to
re-launch it again with all extensions disabled. This is currently
implemented by clearing the list of enabled extensions, which means
the user needs to re-enable their extensions manually again.
To make this process less annoying, add a single 'kill-switch' setting
gnome-session can use without interfering with the user setting.

This is an implementation of the pad OSD that's been previously

Nowadays, the user interface has mostly stabilized with most changes
happening under the hood. As a result, extensions written for previous
versions of GNOME Shell are very much expected to keep working on
updates, if it wasn't for the version check that requires a version
bump in the extension metadata. There has been a setting to disable
that check for a while, but it's existence isn't widely known (hence
the common perception that "everything breaks on updates"). While
there is still some risk that an out-of-date extension can be enabled
without error, but fails spectacularly later (where we cannot catch
the exception), it is reasonably small by now when compared to the
~95% of extensions that can be "unbroken", so swap the default value
to disable version checks by default.

Commit bd6e7f14d1 reimplemented the cycle keybindings to
fix cycling between more than two windows, but the approach
of highlighting cycled windows by actually focusing them has
the drawback that cycling messes up the MRU order of windows.

finishes, and use a dedicated actor that draws a border around
a window clone for highlighting.

If a sandboxed app requests access to some system resource (camera,
microphone, location), the portal frontend needs to ask the user
for permission. In GNOME, we want this to be a system modal dialog,

that exposes a generic system modal permission dialog on the bus.

We currently use the :active pseudo class to mark the selected day
in the calendar. Whenever the selected date changes, the class is
added to the corresponding button and removed from all others.
However when the selected date doesn't change (i.e. when clicking
the already selected date), the buttons are not updated and the
use of the :active class conflicts with StButton's builtin handling
of the class - the class is removed on the button up event and the
button is deselected.
Fix this by simply using a different pseudo class.

If we detected that Bluetooth devices were setup, show the Bluetooth
menu so that users can easily turn Bluetooth back on.
This is a bit of a hack, as we cannot detect whether there is a
Bluetooth adapter at all when it's disabled, so we cannot tell whether
there were any Bluetooth devices setup, at some point. This state is
saved in the gnome-shell GSettings in the had-bluetooth-devices-setup
key.
Checking whether we saw Bluetooth devices at one point is a good
enough guess of whether there will be some in the future.

For menus, it makes more sense to pick a width that fits a reasonable amount
of content rather than a fixed amount of screen estate, so use font-relative
sizes instead of pixel values.
https://bugzilla.gnome.org/show_bug.cgi?id=754581
Some labels in the system status menu - namely network names - are out
of our control, and may thus grow the width "infinitively" unless we
restrict the menu width. So far we have been doing this by setting a
fixed width or max-width, but any value we put there might end up
being too restrictive in some locales. Instead, request a width that
fits all the labels we want to show unellipsized and use that instead
of an arbitrary limit.

We now stopped using notification actors directly for anything, so

Since we stopped special-casing chat notifications to use the old

The .selected style class indicates the "active" menu item, which
is generally the last hovered or focused one (whichever happened
last). Styling that instead of :focus and :hover directly guarantees
that only a single item will be selected at a time, which removes
ambiguity and matches the behavior of GTK+ menus.

Commit 5a8923ef95 removed support for legacy status icons from
the notification system, as we no longer want them to appear as
notifications. As we are unfortunately not quite at a point where
we can remove all support for them for good, so we now need an
alternative place to put them. Add a small dedicated tray at the
bottom which appears when any legacy status icons are active. By
default it is almost completely hidden to not interfere with the
user's windows, but can be expanded on demand to interact with
the icons.

With the message tray no longer being a distinctive UI element,
the existing <super>m shortcut for viewing the notification list

default.

We no longer have a single notification actor that is either displayed
as banner or reparented to the summary depending on state - both the
lock screen and the notification section of the message list create
their own UI based on the information attached to the notification
object. Adding to this that different representations of a notification
may now exist simultaneously (as they are included in the message list
immediately rather than after the banner has been displayed), it no
longer makes sense to keep the banner actor in the notification itself.
Add a new NotificationBanner class that provides a separate banner
implementation based on the message list's NotificationMessage that will
soon replace the existing notification banners.
The message tray is now empty and about to be removed, so an indication
at the bottom edge of the overview becomes an odd location to convey the
status of the summary. We will eventually display an indication in the
top bar that unseen messages are available, for now just remove the
existing indicator.
https://bugzilla.gnome.org/show_bug.cgi?id=744850
The notification list in the calendar drop-down now functions as summary

The sass sources now live in a project in GNOME, so they can
be used in multiple projects like gnome-shell-extensions.
Because of that, add gnome-shell-sass as a submodule of gnome-shell
and remove the sass sources from the theme directory.
This used to be the style-class for status icons (i.e. icon-only
top bar items). It got unused a while ago when the class used
by status icons stopped using it - except for the keyboard indicator,
which set the class manually to appear as status icon despite not
being a real icon.
Now that the button highlight is provided by the .panel-button class
on a parent, the obsolete class results in a double border on the
keyboard indicator when active - just drop it from there as well
to fix.
- the goal is to have the items activate even on the edge
sadly this Fitzsiness is only working on the app vault icon
at the bottom, not the regular icons so far.
So we can style it differently than :hover.
We already have a active state for the menu items which includes
more than hover. For example, when the keyboard focus moves to a item
or we select programatically a item.
For this reason we need a style class named active for the meaning we
give to it in menu items, and a pseudo class active with the meaning
CSS has.

Since widnows decorations with round corners has a special shape,
which when scaled we can't match with a simple border-radius.
So to prevent to show a gap between the caption border and the
caption itself, apply a shadow.
- separator seems to have a semi-opaque top that interfers
with the bottom row of teh calendar
- current day can't have a blue brder on the bottom,
but $borders_color on the sides. Apparently cannot
use non-uniform border colors.
- month pager missing
Currently we animate in both sides, hover on and hover off, and with
200ms. The downside of that it that it feels sluggish when passing with
the mouse hovering few items because the on transition is slow.
Match what gtk did for fix this for list rows hover state at
commit 52e91f1f74ecb943d, animating only on off hover. However,
gnome-shell doesn't support different kind of transitions for its css,
that will be lovely to have a easeOutQuad as well here.
When opening a panel menu, we set it's max-height to the available
work-area height to keep menus with scrollable content from growing
outside the monitor. However a menu that extends all the way down
