Here's an early mockup of TextFileSplitter's new GUI. It will be about 500x800, so this should fit on all netbooks out there. This is just an early design. Still working on it with my designer.

This is a WPF UI. I will need to redo the splitting strategies to use a WPF user control (for configuration) instead of the Winform ones. This is what is holding up the release of TextFileSplitter 3.0
