I re-read the man page (this time all the way through) and realised
that most of this part of my answer didn't make sense in the context
of vis. Here's a revised comment.

So currently `X` is more like vim's `windo`. I use `bufdo` more often,
but there are no background buffers in vis so the situation is a bit

Your use case (closing all the windows) can actually be achieved by
cycling through the buffers and using the `:bdelete` command. This
works because `q` has a special version that applies to all the
windows of the same buffer. This shows a few possible alternatives:

- All appropriate commands have two distinct version: one for window,
one for buffer.
- A wrapper function toggles between the different behaviours (similar
to the `:vertical` command in vim).
- A prefix or suffix to these commands toggles between the different
behaviours (similar to the `!` suffix to toggle behaviour of some

The functions that would be affected: q/delete, earlier/later,
map-window/unmap-window. Any other?
