There really is nothing really wrong with the current one however there are a lot of aspects I dislike.  I find some of the colors too washed out and the fact I used Win32 instead of WPF makes scalable an issue.  I’m chatting with the same guy who designed the first version, Ian Hill, to help redo the UI with me.  WPF will allow me to have non-rasterized graphics via XAML that can scale and won’t be pre-rendered.  It will also let me have animations and some neat flow control abilities out of the box.

I whipped up some mocks on the way to a work event.  Few more are on flickr.

Remember, a great user interface makes all the difference.  Ian rules so I’m asking him again for some help as I am a lonely dev-signer, not a full blown designer.
