Agreed.

IIUC, "layout prev/next" doesn't cycle this layout.  That seems odd.
I think it either should, or this should be a separate command.

A "layout cli" layout could reasonably be a layout that (with tui enabled)
only showed the console window, with status line at the top, similar to
"layout src; winheight src 3" (3 just because one can't go lower
than 3).  I supposed we could leave room for adding that later by calling
this one e.g., "layout off".

I notice that we have no blessed way to go back to the same layout that
was current when the tui was last active.  "layout current" would be odd,
given that the current is "cli"... Hmm, "layout last" (like "cd -")?
Not sure...

A separate command ("tui enable/disable"? "set tui enabled on/off"?)
would be a more direct mapping to the readline bindings.

What do you think?
