Tab Shelf 2025.2.2

Performance regression fixes, improved settings, and custom click actions Jun 11, 2025

Tab Shelf 2025.2.2 is now available on the Chrome Web Store (still pending review on Edge Extensions at the time of posting).

This release focuses on fixing a performance regression and squashing bugs around tab group customization.

Some new features and improvements were also introduced - namely custom click actions on tabs and tab group headers (double click and middle click), a redesigned and easier to navigate settings menu, and expanded customization options for the appearance of tab groups.

New features

  • Added the option to set custom actions when double-clicking a tab, and when middle-clicking tabs, tab group headers, and window headers. You can now set these click actions to mute, sleep, or select tabs/tab groups/windows (amongst a variety of other actions).

Improvements

  • Redesigned the Settings menu with a simple drill-down menu style. This means you will no longer be presented all of Tab Shelf’s settings at one-go by default. This also makes finding specific settings much more convenient as you no longer need to carefully scroll through the menu.
  • Replaced the option to hide outlines around tab groups with a more comprehensive tab group appearance setting. This lets you choose between showing both the outline and shaded background, just the shaded background, or just the outline.
  • Added the option to hide the auto-sleep block icon when a tab is manually set to never auto-sleep.
  • Added an FAQ to section (which can be found in the Settings menu) which addresses common questions or feedback received.

Bug fixes

  • Reduced repeated duplicate tab detection notifications.
  • Fixed performance regression caused by more aggressive duplicate tab detection. Tab filtering and search should also be faster as a result.
  • Fixed hover and selection background color in tab list.
  • Fixed broken tab group renaming modal.
  • Fixed non-persistent tab group color mappings (setting a tab group color sometimes doesn’t appear to work, or sometimes the wrong color is mapped to the tab group).
