Excellent! Great addon, more useful than TreeStyleTab: It has all what you need out-of-the-box. Many preferences with logical structure. Great thanks for Snapshots - It safe me few times and I didn't waste a lot of time for recovering. I especially like a feature to save the whole tree of tabs as bookmark: add with fool folder structure or just as group of standalone tabs. It's beautiful and handsome, no doubts ♥

After rebooting computer - all settings gone

good. It really is one of the best Firefox addons.

But to mention one downside, the Tab "Unload" is inconvenient.

It would be nice if the Unload function could support mouse and keyboard.
1. Please, Support Mouse Click
2. Please, Support Shortcut Key

Excellente extensión. Me encanta su funcionalidad de crear nuevos paneles.

This is such a great addon that I hadn't discovered before. I have been suffering from too many tabs in work for many years and this is such a great extension that helps organize all kinds of things. Kudos for the author!
