I'm not quite satisfied with the new Bitcoin-Qt UI. There are too many mouse clicks and things aren't presented obviously.
Since this project is still new, I'd like to contribute my mock-ups, so that developers can utilize them whatever ways they want.
Disclaimer 1: They are in no way complete (or perfect). Just some personal ideas to fill the blank spaces and reduce mouse clicks. Also, I didn't do any graphical design, so a wonderful product will be the combination of this design and some professional graphics (if I have time, I will make some).
Disclaimer 2: Even though this is done in Mac, Qt should be fairly easily to customize to achieve the same effect. But, please, try to use Cocoa and Windows API for Mac/Windows clients. This mock-up was done using Interface Builder of Xcode.

I don't really know anything about visual development, but I'd like to contribute and learn as much as I can.
