It's out of scope to start another thread about the core purpose of liqbase here, but the purpose of the hackfest is precisely that others tell you how to improve the concept/usability/graphics of your project.

After all this time and all this fuzz liqbase still is far from having delivered a product, even if it contains all the elements to become a successful product. Probably a core problem is the lack of a crispy concept, and I'm not the first one telling you this (neither for the first time).

So I would say that if you want to keep having your own "liqbase framework" approach in the lines described above, fair enough. If instead you are welcoming external ideas to get that sketch based application organizing your stuff neatly in a visual calendar, then your project is a good candidate for Friday.
