At first I found it difficult to get a tab into a group. It's pretty finicky about just how overlapped it needs to be to group rather than reorder. I think it would be better if it were a little easier to group and a little harder to reorder tabs.
Also, I had a playlist that included some YouTube pages and some YouTube Music pages. When I put them all into a group, the YouTube pages gave the name of the video but the YouTube Music pages only said "Youtube Music". Not sure if that's a bug or an issue with getting info from YouTube Music.
