That tabs can be naturally used for managing stacked panes of content does not
mean that they should only be used for that. I see no contradiction between tabs
as "buttons" and tabs as selectors for stacked panes.

The former is more general, that's all. However, I would not like to see the
current Emacs tool-bar and its buttons as the model for Emacs tabs. We can do a
lot better. (See my other mail on this today.)

Well, "pane" kinda implies "window", so it's hard to argue with that. But Emacs
has lots of _sets_ of content (visible or not), and letting a tab select for
such a set of content is part of what I would like to see. I do not want to see
Emacs tabs being only about window selection (whether individual windows or
window configs).
