I've added the following features (you can find all of them in the menus):
- extended undo system to faceselect mode and the image window
- hide function in the image window (for selecting faces in the image window)
- heal uv (merge texture vertices by mesh vertex). can also be based on distance to do a 'global heal'
- island select (think atlas uv map, basicly works like 'select linked')
- unlink selection (only select faces in the image window, that were fully selected). should be usefull when you want to take a piece off an island
- proportional editing in the image window
- Hidden Bonus Feature
