But how would a user customize switching from the `right-only' to the
`bottom-only' state?  How would a user specify the preferred initial
state?

I initially wanted to add just a simple menu entry for switching.  For
that I wanted an option which allowed to select one of four permissible
states.  Obviously, that option would have to be customizable via the
`customize-variable' interface as well.

Then I noticed that all items in the Show/Hide group are minor modes.
Some of them in a contorted sense - both `fringe-mode' and
`mouse-avoidance-mode' are simple defuns.  I would have preferred to do
it their style, possibly using completing read.  But I tried to be a
good citizen and specified `window-divider-mode' in a sense similar to
`scroll-bar-mode' - the only mode I found that was specified via
`define-minor-mode' and allowed more than two values.

Now if I'm not mistaken you seem to say that the approach I've chosen is
not TRT.  But how can I know what TRT is?  Neither the various modes one
can activate via the menu bar nor the manual provide useful guidance in
this regard :-(
