Tab Grouping needs So much improvements

HotCakeX I figured a month had gone past and it was time to look at Tab Groups again, so I just enabled them in the latest Dev build.

Well, they are a bit better than they were but it's still a clunky, manual process and Tab Groups don't seem to have any persistence mechanism -- if you close the group, you can't reopen the whole group (just individual tabs from it). You can't save the group as a favorite. If you open a brand new tab with ctrl+T and then go to the same website as one that is in an existing tab group, it doesn't automatically join the group. You can't create a new group until you have a tab open. You can't open a favorite into a tab group.

It seems like a really weird feature.

I'd dismissed it as simply "experimental" last time, since I don't even remember it being announced as a new feature, and it didn't seem to have enough functionality to be useful.

I'd love to hear somewhere from the Edge team explain what their vision is for this feature!
