I'm sorry, I understand the quantum updates required a full rewrite for all tab related extensions, but this (and its companion tree style tabs) is just buggy to the point of being unusable. Even something as simple as selecting tabs in the dropdown menu is broken; selecting a single tab doesn't work half the time and it's a miracle if you can actually select more than two or three without the selection randomly changing, and even IF you can manage to select all the tabs you want, most of the time the action doesn't get applied to the entire selection. The inability to get such simple functionality working reliably is, frankly, bewildering.
