I like this idea.
Graal never felt like much of a Mac program. It has a very (no offense) cheap, Windows feel about it. When a Windows program is ported to the Mac, without applying certain Mac aesthetics, it seems to look cheap. Without things like the lack of Mac keyboard support, minimizing, and other features described here, it doesn't feel like a Mac app.
Maybe it could even have support for Growl notifications?
Im not sure what it was coded in on the Mac, but if it was Objective C and Cocoa, it should be relatively easy to add more Mac-like features, no?
Then again, it also shouldn't be too hard to make a Mac level editor
