So you're saying that pressing 2 on screen buttons, then closing a page is a better solution than creating a group then dragging in and out whatever you need? Sure, I use the bookmarks bar too, but it's not for stuff I'll remove after a while, those are perminent, but tab groups are generally for stuff you will eventually close, but wantto sort in the meantime to make it more convenient.

If you don't have a use for it, fair enough, I don't either, but it is a genuinely useful feature for some that can't be replaced by more clicks.
