Author here. That's not quite what I meant; mapping keystrokes to Vim's tab commands is well and good, but it requires some serious kludges to make Vim behave the same way as, say, Notepad++, where one open tab equals one open file, and that's that. "Window groups" would have been a far more accurate though potentially less familiar name for the feature, in my opinion. I don't actually use tabs much, personally. I seldom have more than three or four files open at a time.
