I downloaded the devcoin client in the OP.
Overall, it seems okay so far (indexing the ~118K blocks will take much more time). However, there are some minor cosmetic errors:
1. The taskbar logo, the window icon and the "About Devcoin" logo are I0Coin.
2. In "Sign/Verify Message", the "Devcoin addresses" are actually I0Coin addresses.
3. "Pay To" says "Enter a Bitcoin address".
Other than that, I don't see any major problems. I'll wait further until the reindex is complete to update this post.
Fixed points 2 and 3 in 1.0.1, thanks.
For point 1 we will have a bounty of I think 8 shares for the new qt images and 4 shares for second best... the images we need are in the original post of this thread.
