Showable

  shows text or figures or whatever

  Examples
    Label
    Canvas
    ...
    basically everything but plain Windows (that only provide space)


Clickable

  passes an explicit event to some external (non-GUI) code

  Examples
    Button

select one from a series...

That sounds odd, since you mentioned them separately...

== Rangeable, over [true, false]
== Selectable, with only two options.

I'm not saying we don't need another widget/layout, but it could be
fancy dressing for certain (most?) style sheets.

== Selectable, due to the range :)  (I'm kidding, here)

Dunno what the notebook is, but I suppose it has a horizontal or
vertical separator that the end-user can move. This is lacking in
older toolkits, I think. Otoh, this is layout mgmt, so we may well
need a sligtly different abstraction.

What is the place of the layout manager?
