really nice, the application 'taste' like any other tablet/cellphone apps should 'taste'. This kind of programs must be considered like games.
Ill look forward for the source releases and see if I can use some of the code there: screen managments, how it access some os things etc) since I suppoese Gary with liqbase will focus on developing a complete application more than create an usable library.
I would move the setting icon from the main menu (maybe move it to the bottom and make it always accessible) and make the ui a bit more responsive interrupting the 'transitions' effects each time the user generate an event: all the animated GUI's I tried have this problem, I cant tap 3 time fast on something without having to wait the end of the effect between each tap. I dont want to adapt to the application time (and often is impossible to have an idea of how much time is needed for something to happen), the application should adapt to me...

I love the site to create online the deb for the themes. That's really appealing for graphiconly people .
Ill check how easy is to write canola's plugins.

Excellent work
