Nevertheless, I agree that Inkscape's basic appearance is quite frightening on the mac. I would vote for applying a theme that is Mac'ish but is not "king of aqua" (because we cannot reproduce exactly aqua anyway) while respecting user level configuration files.
In fact I do that already and use Inkscape (and Gimp BTW) with a GTK theme derived from a Mac ShapeShifter theme called Milk,
What do people think?
I'm personally fine with it. Inkscape is not a Cocoa app, and shouldn't be expected to look or act just like one, but if it looked better, it'd be more pleasant to use :-)
My wife has finally gotten quite good with the Gimp, and I'm trying to get her to start using Inkscape more since it'd be more appropriate for some of the stuff she does. I think there's something of a UI-shock when switching -- even though Inkscape's controls and layout are much better and more intuitive than the Gimps.
Thanks,
