I'd like to use the new Tab Groups feature, but without the option to use tab groups like "tree style tabs" I can't get used to it It'd be magical to auto-create a group when I open a link from a page.
I usually have this feature with the 'mailmindr' extension. It worked well, but now it's not compatible with the latest Thunderbird versions. It'd be nice to have it integrated.
Finally! Thx! I like the first approach and the feeling, and I hope you will be implementing one of the big avantages to use vertical tabs: tab grouping / tree style tabs.
