I look forward to when this can handle my everyday use as tab groups did. Right now it does not do what I need. I cannot easily move tabs between groups, cannot name my groups, and when I select another group I have to wait for all the tabs to reload which really slows things down. Also, if I have music going in a tab and I switch groups, the music stops. So right now it's a no-go for me, but I'm hopeful for the future of this Add-on cause I'm really missing tab groups since the Firefox Update.
