Everything is feasible given time :)

Weird ideas are a source of inspiration for the developers when they want to
work on something ;) That doesn't mean all ideas will ever get implemented.
Btw, our ideas brains storming usually end up on our wiki
(http://wiki.koffice.org/index.php?title=Krita ), do you have any problem if
we put your mockup there ? The license is

And why not rotate and skew directly the brush outline ? It could be done in a
similar way than "shape" manipulation in koffice2 (see below for an
Spacing and opacity could then be manipulated using the wheel.

Well the "toggle between modes" should follow the manipulation of shapes, that
means "handlers for everything".

Yes that's true, you are more concerned with the shape, that's also why I
wondered if defining a size in the brush is trully needed. Or if it could be
defined by the tool/paintop when the artist starts using the brush.

Not really, because with 1 you are still altering some other settings outside
