4.0.1

• 4.0.1 (2024.3.8)
  • Tabs containing sticky tabs are kept expanded when another tree is expanded, even if those tabs are sticked via API.
• 4.0 (2024.3.7)
  • Improved performance on cases with large number of tabs. Now tabs only in the viewport are rendered.
    • Pinned tabs and unpinned (normal) tabs are now placed under separate container elements: #pinned-tabs-container > .tabs.pinned and #normal-tabs-container > .virtual-scroll-container > .tabs.normal.
    • Each rendered tab element now has data-index attribute corresponding to tabs.Tab.index.
    • Due to this design change, customization with CSS counter won't be work as expected anymore. You'll need to create something helper addon to do such customizations.
  • Introduce new context menu commands and other triggers to stick arbitrary tabs to edges of the tab bar. It is similar to "Pin/Unpin Tab" but sticked tab keeps its tree.
  • Indicate sharing state of tabs (camera, microphone and/or screen) with icons.
  • Show dropshadow before normal tabs when the tab bar is scrolled.
  • Show dropshadow after normal tabs when the tab bar is not fully scrolled.
  • Use cached tree structure information more aggressively on Firefox startup, if the number of tabs, pinned status, and containers are matched.
  • Add ability to control tabs opened from Firefox View.
  • Suppress bookmarks folder auto creation for bookmarks from tabs, when multiple bookmarks are copied via the Library or something way.
  • Move descendant tabs also correctly following to their parent, when a parent tab is moved to the top level via Firefox's horizontal tab bar.
  • Apply the option to place opened tabs next to the last related child correctly, when multiple tabs are opened from a pinned tab.
  • Avoid unexpected restoration of blank dialog windows by Ctrl-Shift-T on Firefox 116 and later.
  • Restore tree structure more correctly for reopened tabs which were closed at a time.
  • Lock scroll position temporary when a tree near the tab bar end is collapsed, just like as the case when tabs are closed.
  • Open local files in tabs with blob: URL when they are dropped to the tab bar, instead of simply ignored.
  • Never create needless multiple folders for bookmarks created from tabs tree.
  • Most options are now treated as expert options and hidden by default.
  • Many API improvements.
    • Introduce a new message type get-version to know the version of TST itself.
    • Introduce new notification types tabs-rendered and tabs-unrendered to observe tabs' rendered state.

    • Introduce a new notification type tab-sticky-state-changed to observe a tab is sticked or unsticked.
    • Introduce a new option rendered:true for the message types get-tree and get-light-tree, to get information only about rendered tabs.
    • Support bulk messaging to TST (sending multiple messages at once) and bulk messaging from TST (receiving multiple messages at once for better performance.
    • Add ability to minimize tree item information contained in notification type messages, to reduce messaging cost.
    • Introduce new keywords allVisibles and normalVisibles for message types get-tree and get-light-tree, to get specific state tree items.
    • Introduce new options states and statesNot for message types get-tree and get-light-tree, to get specific tree items.
