It might be nice if there were a “undo tab close” command, or a list of recently closed tabs that you could click on to restore the tab. Basically duplicate the same functionality as Firefox browser tabs (including ctrl-shift-t hotkey).
The use case is slightly different than the “open recent” menu (as you might have accidentally closed a file that you’ve been keeping open for reference, but haven’t save in a while so it wouldn’t be in the recent file menu. I just did this, and almost pressed ctrl-shift-t out of habit to try and get it back (my web browser has conditioned me to this).
