Most useful addon/extention in the store!
IT IS A MUST HAVE & SHOULD BE NATIVELY INTEGRATED IN ALL BROWSERS!!!

However i have some recommendations:
1. More settings for customizing the manage groups view.

edit: And we need Subgroups :D

1.1 Fold/Unfold a specific group or a pair of groups (fold custom topic 1 only) the folded group now only shows custom number of entries [i have too many groups they dont fit onto my screen at once, even with my 1,20 meter wide monitor+second monitor setup lol]

1.2 Highlight tabs that are currently loaded (text color+backround should be both customizable to avoid people in dark mode or with dimmed screens seeing the difference)
