Hi Echo I've been reading your application and it looks right to me. One thing I see is that you have selected gwt-platform instead of the core mvp in gwt but you don't say any reason about why you prefer the first option. Also I'd like a deeper description of how you pretend to face new features, I mean components, persistence, customization etc.
