A lot of convenient functions, a lot of settings! This is a very good FF add-on

It would be perfect for me, but despite the many settings - it looks very rough.
What I didn't like:
Each group must be configured separately. Author, please make it possible to create a template for new groups or an editor for the view of several / all groups. When working with multiple groups, it becomes very slow (((
When you drag and drop tabs, a menu appears that allows you to do anything but merge tabs into a group (or move them to a group on the thumbnail).
The group string has no separators if you use a solid background it looks bad.


P.S. I still use another extension, but I really hope that someday I will return to this addon and be able to use it with joy. (the PRO version of course)
