This would show all tabs within a tab group as a list within a column, similarly to how Tab Groups Helper used to look like:

This really helps when you have many tabs within a group by showing all your tabs in the window, as well as reduced browser load from showing so many thumbnails.
I think that I can do it. Wait this feature in new versions.
This would be great to have especially when "capture thumbnails for tabs" is turned off.
This would be especially helpful to enable selecting multiple tabs at once to drag-and-drop into a new tab group as well.
Tilted tab group is doing something like that (but is very buggy at the moment):

Fixed.
Sorry for making you wait...
