At this path you will create a parallel desktop...

Have you considered to have a core subset of features around sketch, camera, doc view and graffiti wall only? These are the functions that imvho make liqbase stand out and they still need a lot of user friendly love.

Then the rest of pieces you and others are willing to play with could be additional plugins or separate apps/widgets build on top of the same base.

Like this app launcher. It's sweet but

a) Does the user really need it when what she wants is to draw a skets on top of a picture?

b) Being a launcher it should be available instantly after one click anyway.

Same for sketching, the user wants to be able to sketch right away. liqbase launch, stars and general menu are already in the way.
