Track KWin Overview through the activeEffects DBus property and expose the state to Folio QML. Hide the workspace frame, dock overlay, and in-containment favourites scrim while Overview is active so the effect does not show Shift shell chrome in its desktop view.
Set the state before invoking the Overview shortcut from Folio so the chrome is already gone when KWin starts composing the effect. The convergence dock invariant now guards both the hide rules and this ordering.
Show a trash icon to the left of the Overview button in convergence
mode. The icon toggles between user-trash and user-trash-full by
watching ~/.local/share/Trash/files via FolderListModel.
Left-click opens the trash in the default file manager via
Qt.openUrlExternally("trash:/"), making the feature file-manager-
agnostic. Right-click offers "Open Trash" and "Empty Trash"; the
latter shows a confirmation dialog before invoking KIO.Trash via
D-Bus.
The right wing of the virtual-desktop pager shifts left to make
room for the trash button.
Show running windows in the app drawer with previews, window
actions, and virtual desktop controls. Hide dock task icons while
the panel is open so the same windows are not duplicated.
Use TaskManager to move windows between desktops, and expose
desktop activation through the containment.
In convergence mode the separate navigation panel is redundant
with window title-bar controls. Remove it by setting its
thickness to zero and visibility to false, then embed Home and
Overview buttons at the left and right ends of the favourites
bar. Running application icons with context menus are shown
between the favourites and the Overview button.
Add HomeScreen::triggerOverview() to invoke the KWin Overview
shortcut over D-Bus so the homescreen containment can open it
without access to the task-panel Plasmoid.
