I can't promise anything with regards to large feature additions. My focus 
will be releasing this software at all and the port to Qt Quick 2. Which will 
be, if done thoroughly, quite a big task. There is lot of QPainter use in the 
components, which isn't exactly encouraged in Qt Quick 2.

I would avoid large feature additions before the Qt Quick 2 port and before 
the related technical decisions are made.

It would be certainly great to have such a large user like Calligra, but for 
that the project's scope has to be extended significantly. So far I have 
designed the components for the "casual" chart user, like visualizing the 
training progress in KTouch or artikulate. It is unlikely that will be able to 
achieve that on my own.

This is certainly possible in Qt Quick 2. Maybe not entirely with QML but one 
can extend the scene graph with new 3D node types in C++. But I personally 
have exactly zero experience with 3D programming.
