Harmy, will there be a workprint release of the version with updated colors and non-rounded edges? I think it would be good to have everyone giving you feedback on the most up to date version possible (if such a thing could exist before this weekend, that would work out great for something coming up on my end).
Oh, and I neglected to chime in earlier, but I think the first official release you do should probably be named 2.0, since 2.1 would probably confuse people without the existence of a 2.0 (you could explain this till you're blue in the face, but who wants to be blue in the face?). Any tweaks made after that could go into a 2.1 if needed (and you have the option of releasing updates all the way through 2.4, God forbid), and then lock in all your changes and make a final 2.5 release (same pattern with Jedi would make for well rounded consistency across the whole project). Even though your efforts are more in line with what 2.1 was, I think jumping over 2.0 will just cause you more headache than it is worth in the long run.
