Hello! thanks for your work on this wonderful addon

I wanted to request two feature additions:

Other tab group: This would function as a catchall for other tabs that are not part of any other groups. this would keep things tidy in the physical spaces between tab groups

Rule ordering: It’s unclear to me how a tab is evaluated if both “github.com” and “github.com/issues” are rules that assign to different tab groups. In this situation, having rule ordering would be a great help.

Thanks so much!

Very useful add-on to make tab groups really practical for everyday use.
Currently I still see some glitches, especially when adding/editing regexes, where the add-on claims the rule was added when in fact it wasn't (probably due to a parse error in the expression).
Feature ideas: Add a full screen page for configuration with better overview when you have a lot of rules.
Offer config sync across multiple firefox instances using Mozilla sync.
