It would be worthwhile to consider this kind of thing for gradients
and palettes, too -- personally I find I often simply want a scratch
area; and being required to create a new palette first is a bit
troublesome, especially since I usually don't want it to be saved. I
could write a plugin that clears a specific palette and then switches
to it, that would be good, actual infrastructure in GIMP for
scratching around would be better.
