A superb add-on! I was using another Tree Tab add-on previously and came across this one - and it has just plenty of settings and possibilities to organize your work and your tabs. Now I'm able to easily group tabs to separate panels (Home/Work/Spouse) each having an isolated storage (container), which allows to be simultaneiously logged in to Google services with different accounts. There are plenty of customization settings, starting from custom icons and to fully customized behavior. I spent some time first to understand how to use all these, and still haven't explored all the possibilities, but I keep discovering still more and more convenient features (like reloading tab using long left click, or grouping tabs to a special Group tab, which shows an overview of all the contained tabs, or unloading a bunch of tabs to reduce memory usage). So couldn't help writing a review - and definitely recommend it!

This is my favorite addon and new redesign is amazing

This is the greatest extension ever made. Look around in the settings and you will find more and more reasons to love it.

The best "tree tab" extension. It runs smoothly and has a lot of customization settings.

相当优秀，找了很多， 就你合适我，哈哈

Probably the definitive tree tabs addon. Very customizable.

This add-on is almost perfect! the one thing im missing and hope you can work on it , is the possibilty to stick/pin tabs like normal tabs. I Know you can pin a tab but it moves to the top like an icon and doesnt stay in its horizontal view with its title.
An idea: to be possible to stick tabs in horizontal view like normal tabs and the possibility to add a custom name for it, so it can work like a Shortcut in list view.
(because to add it as a bookmark has another behaviour and envolves another panel)

Also if it could be possible to show all panels tabs in tree view (with their name and color) one under another to avoid having to click in each icon to access the panel and then the Tab.

Thanks a lot for your work!
