User reviews

Tabs Outliner is praised for its powerful and unique tab management features, especially useful for heavy tab users needing organization and session saving. However, many users report critical issues due to lack of maintenance: data loss, broken features, and an outdated UI. Support and communication from the developer are poor, resulting in frustration. While the extension remains valuable for some long-term users who can troubleshoot, potential users should be cautious about data safety and maintenance status.
Pros
  • Excellent tool for organizing and managing large numbers of tabs with a unique tree-style structure.
  • Supports saving and restoring sessions, helpful for multi-tasking and research projects.
  • Allows adding notes and renaming tabs for better organization and memory aid.
  • Provides options for backup, especially in the paid version, including Google Drive integration.
  • Long-term users find it valuable and effective despite a dated user interface.
Cons
  • Extension appears to be abandoned or very infrequently maintained, causing bugs and breakage with recent browser updates.
  • Users report complete loss of saved tabs and data, often without reliable backup or recovery options.
  • User interface is outdated, clunky, confusing, and difficult to use especially for newcomers or those with attention difficulties.
  • Basic expected functionalities like reopening tabs/windows with double click are broken or inconsistent.
  • Developer is unresponsive to support requests and has removed community resources, frustrating paying users.

hope can support chrome tab groups

I can't re-open my tabs or window with double click. This is one of the basic functions I need and it doesn't work. Sometimes it would but I couldn't figure if I had to have the cursor positioned a specific location or what the trick was. Led to cursing at the computer and that's unnacceptable. Holding Ctrl or Shift didn't work either. Really disappointing because the organization options are great.

DO NOT GET THIS EXTENSION! It no longer works and all those saved tabs over the years appear to be gone. DO NOT WASTE YOUR TIME!
