That's a good start :)

I'd like hearing from them, of course

I'm not sure what you mean with a configuration widget. Do you mean
custom widgets?

Well, I can easily imagine myself applying Curves to a group of vector
objects ;-)

4) and 5) seem to be related, so one answer to all of them. I'm
talking about effects plug-ins like Red-eye Removal, Softglow,
Colorization, Desaturation etc.

Of course, and I'd like to make sure that GIMP's developers stay tuned
from the very beginning, if they like this idea, so that their design
decisions are to benefit all of us ;-)
