i think (and I have thought and discussed about it quite a bit with
usual suspects like alexia and pippin) that trying out is best done
with the full parameters of _this_moment_, on the canvas or a copy
of the canvas. after I attended a sprint with krita, they have
implemented a variant of that. you can see blogs about that.

for a vector brush, yes. pixmap: I believe not.

after reading that a couple of times, I think you
are talking about making a vector brush from scratch for temporary use.

I think we want to have the 'from scratch' mode mutual exclusive with
the
'from collection' mode. this separates nicely the 2 modes users are.
this must be done by switching the mode at the top of the brush
selection
dialog (a copy of which also pops up in the tool options). of course a
'from scratch' brush can be saved into the collection. then it has
become clear
that the 'from scratch' mode is equal to the brush editor (which can
definitely use improvements).
ah, and when you implement a pattern like that, you will be required
(I bet)
to make the changes in such a way that they get applied to all resources
(patterns, gradients, etc).
