User Reviews

User feedback highlights Tabby as a useful and accessible window and tab manager appreciated for its simplicity, with several reviewers choosing it for daily use. However, reliability problems with moving tabs and occasional compatibility issues (notably on LM22.2) recur across multiple reviews. UI quirks like a scrollbar covering the close button and a lack of group-based tab filtering are also noted, along with some confusion around renaming windows. Improvements in reliability, compatibility, and feature parity would make Tabby a more consistently strong option.
Pros
  • Useful and helpful for managing windows and tabs
  • Easy to use and lightweight with a simple, accessible interface
  • Accessible visuals that aid navigation for users with visual fatigue
  • Generally good tool for window and tab management
Cons
  • Tabs moving between windows is unreliable or breaks in several cases
  • Compatibility issues on some systems/versions (for example LM22.2)
  • Scrollbar covers the close button, making it hard to close windows
  • Lacks a feature to show only non-hidden tabs from the current group
  • Renaming windows is not intuitive and requires navigating a dropdown, causing confusion

Tab move doesn't work which is the reason why I installed the extension in the first place. Not only does it not work, it moves other tabs to other windows.
