I just noticed -- the foreground color can currently be changed during
painting, and the change immediately takes effect -- old paint is still the
old color, new paint uses the new color (even for the ink tool); You must
trigger the plugin to change the FGcolor before you start painting, though.
What is stopping the actions (such as 'swap FG/BG colors' 'next color in
palette'...) from being activated during painting? Is this a GTK+ limitation
or something that GIMP does?
This ability is very useful to speed up painting (see MTPaint,
http://mtpaint.sf.net)), and for mouse users, the ability to change the
brush scale or opacity during painting would be even more useful.
