My GWT / GAE Project

I created a little WebApp to combine and cut Youtube Videos with the Google Web Toolkit running on the Google App Engine. I basically build it to get to know the technologies. But I think that it might be useful for somebody.

I would really appreciate any tips on how to improve the design / user interface. Furthermore it would be awesome if some of you could try to create a video and post ideas on how to improve the general concept.

Thanks,
