Tab group persistence, and auto-grouping by hostname

This is a feature idea I had. I hope someone who works on UI design considers it. 1 - Persistent groups I use vertical tabs, and I like the idea of tab groups, but I never use them because I don't want them to be ephemeral. As a user, if I'm going to be spending time organizing things with this feature, having tab groups disappear after closing all tabs makes me fee like I've wasted my time engaging with the feature. Tab groups have to persist until users manually delete the group. I'd like for groups to persist even if they have no tabs in them. They are categories with a name in which I would like to organize my browsing, but I'm not going to waste time organizing if I'm going to lose everything by closing tabs. 2 - Auto-grouping new & existing tabs by host name (excluding pinned tabs) When creating a group, I would like a toggle in the group options ui (where you pick the color and name), to make the group a catch all for any tab opened with the same host name (it would auto-add new tabs with the same host, or existing ones at group creation time). As a matter of fact, when creating a tab group by dragging a single tab over another single tab, when both have the same host name, they should auto toggle on the filtering by host name. I think this feature would get more use with either of the above changes Alexandre Leduc
