Our New Main Dialog

So, I'm finally getting round to making some UI improvements to the main dialog in Typecast. This dribbble and the attached screenshot of work in progress give away quite a lot about what features we're planning to work on in the near future.

There are 3 things I am trying to achieve here:
1. A more natural grouping and visual priority for most used features
2. Further interaction affordance for drag, hover, click etc
3. A more settled set of patterns for common controls

Let me know what you think about the new look, organisation and features.
