Summary by Sourcery

Add a new Fashion dock alignment mode with floating compact layout, introduce folder groups and card plugins to the taskbar, and implement a robust overflow system for taskbar items while refining positioning, drag-and-drop, and popup behavior across the dock.

New Features:

• Introduce Fashion dock alignment mode with floating, compact taskbar layout and updated blur/background styling
• Add support for folder groups in the taskbar, including composite icons and a grid-based folder popup for launching apps
• Implement adaptive taskbar overflow handling with an overflow button and popup to show hidden application items
• Add card-type tray plugin support with a dedicated left dock carousel area for card surfaces

Bug Fixes:

• Improve dock and tooltip positioning for cross-window scenarios to ensure previews, menus, and popups align correctly with dock items
• Ensure hidden delegates in overflow do not affect layout sizing or spacing
• Prevent taskbar text width calculations from running when disabled and stabilize updates via deferred computation
• Allow panel popups to stay open during interactions by making auto-close on inactive configurable and fixing menu race conditions

Enhancements:

• Extend dock alignment settings and serialization to include the new Fashion mode, updating indicator style behavior accordingly
• Refine taskbar space calculation to use an effective center space that respects edge spacing and Fashion mode margins
• Adjust drag-and-drop behavior for dock items and launcher elements, including support for dragging folder groups and internal moves between taskbar and overflow popup
• Update app grouping logic and identifiers to use validated "internal/folders" IDs, ensuring consistent group management and persistence

Build:

• Link the taskmanager library against Qt Quick and register the new TaskOverflowController type for QML usage
• Add build configuration for the new card-left dock package

File-Level Changes

Change	Details	Files
Add dock "Fashion" alignment mode with floating, compact layout and updated blur/indicator behavior.	Extend ItemAlignment enum and string conversion to support FashionAlignment, and expose a fashionMode property from DockPanel. Update the main dock window sizing, anchoring, margins, and exclusion zone to implement a centered floating bar with animated width and rounded corners when fashion mode is active. Adjust grid layout, center-area spacing calculations, and left filler visibility so the center section and right part pack into a compact floating strip in fashion mode. Switch StyledBehindWindowBlur and window radius to use fashion-mode radii and DTK palette defaults, and add a fashion-mode entry to the alignment context menu. Hide the show-desktop applet and task manager’s remaining-space logic in fashion mode, and ensure animations fall back to size-based transitions when needed.	panels/dock/constants.h panels/dock/docksettings.cpp panels/dock/dockpanel.h panels/dock/dockpanel.cpp panels/dock/package/main.qml panels/dock/showdesktop/package/showdesktop.qml
Implement taskbar overflow controller, overflow button UI, and make delegates/layout overflow-aware while improving popup positioning and drag-and-drop behavior.	Introduce TaskOverflowController C++ type (registered to QML) that computes visible item count and overflow popup model from available extent, spacing, and item size, with hysteresis and async sync. Integrate TaskOverflowController and TaskOverflowButton QML into TaskManager, marking hidden delegates as zero-size so they don’t affect layout, and wiring an overflow button that shows hidden apps in a popup grid. Extend task item delegates (AppItem.qml) to support dragSource/dragEnabled, improved drag-finish handling, and preserve panel popups when opened from overflow, and adjust tooltip/preview positioning via updated DockPositioner APIs. Enhance TaskManager.qml drag-and-drop to support items originating from both taskbar and overflow popup, including index mapping, reordering, and scheduling overflow resync after moves. Add cross-window-aware geometry handling in DockPositioner/DockPanelPositioner (effectiveBounding, attachedItemRectInDock) so tooltips/previews align correctly when dock and popup live in different windows. Update OverflowContainer calculations to ignore zero-sized (hidden) items in implicit width/height. Improve PanelPopup with a closeOnInactive flag so popups used during context menus/drag remain open until explicitly closed.	panels/dock/taskmanager/taskoverflowcontroller.h panels/dock/taskmanager/taskoverflowcontroller.cpp panels/dock/taskmanager/taskmanager.cpp panels/dock/taskmanager/taskmanager.h panels/dock/taskmanager/package/TaskManager.qml panels/dock/taskmanager/package/TaskOverflowButton.qml panels/dock/taskmanager/package/AppItem.qml panels/dock/OverflowContainer.qml frame/qml/PanelPopup.qml panels/dock/dockpositioner.h panels/dock/dockpositioner.cpp panels/dock/taskmanager/CMakeLists.txt panels/dock/MenuHelper.qml panels/dock/taskmanager/package/AppItemTitle.qml
Add folder group items to the taskbar backed by launcher folder models, with composite icons and folder popup to launch contained apps.	Extend DockGlobalElementModel to accept a launcher group model/provider, treat internal/folders/* IDs as group elements, and expose group-specific roles (name, groupItems, docked state, menus). Implement helper methods in DockGlobalElementModel to resolve folders into names and app lists (using both launcher and app models), keep docked folder entries in sync with group-model changes, and allow docking groups via requestDockGroup. Teach TaskManager to recognize canonical launcher folder IDs, dock/undock them via dockedElements, launch apps from groups, and handle folder IDs when saving dock order. Update AppsApplet to expose groupModel and new invokables for groupItemDetails and launchApplication, used by the dock to resolve folder content and start apps. Adjust AppGroup/AppGroupManager to use the new internal/folders/ID scheme, robustly parse/assign folder IDs, and ensure the top-level folder definition is present. Extend AppItem QML to detect group items, render a composite preview icon grid, open a new FolderPopup at the icon position on activation, and delegate group app launch requests back to TaskManager. Introduce FolderPopup.qml, a grid-based popup showing folder contents with scroll, hover/press styles, and item activation wired to TaskManager.launchGroupApplication. Update TaskManager models/roles and globals (GroupItemsRole/MODEL_GROUPITEMS) so QML delegates receive groupItems data.	panels/dock/taskmanager/dockglobalelementmodel.h panels/dock/taskmanager/dockglobalelementmodel.cpp panels/dock/taskmanager/taskmanager.h panels/dock/taskmanager/taskmanager.cpp panels/dock/taskmanager/globals.h applets/dde-apps/appsapplet.h applets/dde-apps/appsapplet.cpp applets/dde-apps/appgroup.h applets/dde-apps/appgroup.cpp applets/dde-apps/appgroupmanager.cpp panels/dock/taskmanager/dockgroupmodel.cpp panels/dock/taskmanager/package/AppItem.qml panels/dock/taskmanager/package/FolderPopup.qml panels/dock/taskmanager/taskmanagersettings.cpp
Introduce card-style tray plugin type and a left card dock area that carousels through card surfaces in fashion mode.	Extend TrayPluginType enum with Card and make DockCompositor track cardPluginSurfaces separately alongside tray/quick/fixed surfaces. Add CardLeftDockArea QML applet that, in fashion mode, replaces the traditional left dock area with a fixed-width, rounded container showing card surfaces in a vertical SwipeView. Implement hover background, swipe and wheel navigation, and a rotated PageIndicator reflecting the number of card plugin pages. Ensure card surfaces receive updated geometry and global positions via a ShellSurfaceItemProxy wrapper and timed sync when the layout or current page changes.	panels/dock/constants.h panels/dock/DockCompositor.qml panels/dock/cardleft/package/CardLeftDockArea.qml panels/dock/cardleft/CMakeLists.txt
Refine text width calculation for window-split layout and guard text measurement when titles are disabled.	Change TextCalculator to debounce recalculations via a single-shot QTimer, reset widths when no space or items, and emit optimal width and total width signals only when values actually change. Disable TextCalculator in fashion mode and when not in horizontal top/bottom positions, and ensure AppItemTitle passes empty text when disabled so it doesn’t affect layout measurements.	panels/dock/taskmanager/textcalculator.h panels/dock/taskmanager/textcalculator.cpp panels/dock/taskmanager/package/TaskManager.qml panels/dock/taskmanager/package/AppItemTitle.qml
Miscellaneous behavior and robustness fixes around docked elements, drag/undock, and IDs.	Allow TaskManagerSettings::isDocked to handle both desktop/* and internal/folders/* elements and adjust comments accordingly. Update taskbar DND to support launcher folder IDs, centralize dockItemId conversion, and only auto-dock on valid targets, correctly handling internal vs taskbar/overflow drag sources and returning appropriate drop actions. Ensure MenuHelper sets activeMenu before opening to avoid races, and tweak copyright headers and minor logic around app trash tooltip calculation and top-level folder creation. Wire fashionMode change notifications from DockPanel when position or itemAlignment changes so QML can reactively update mode-specific behavior.	panels/dock/taskmanager/taskmanagersettings.cpp panels/dock/taskmanager/package/TaskManager.qml panels/dock/MenuHelper.qml panels/dock/dockpanel.cpp applets/dde-apps/appgroupmanager.cpp applets/dde-apps/appgroup.cpp applets/dde-apps/appsapplet.cpp
