How difficult would it be to add this feature to Synfig? gcolor2.sourceforge.net/ I really like using it in GIMP and Inkscape. I would add it myself if someone could tell me how. Anyway, we definitely need to include this in the next release. Thanks guys!
Hi jsfarney, regarding gtk color dialog, there was a long discussion before in our forum, I hope it can answer your question in some way.
