Do you mean the distinction between getState() and getCombinedState()? I 
implemented it that way because I felt that we may need to now the 
actual state of a widget and not always the combination with it's parent 
state according to the state priority rules.

Ok, waiting :-)

Good idea. The various isXXX methods on WidgetState are meant to avoid 
direct reference to actual state constants within the code. That firstly 
avoids inconsistencies and also allow later extension if needed (once 
again, I think we'll need to add an "output" state).

So go on merging in the stable branch!

Good idea, but rather than your page or WoodyScratchpad, what about a 
new CFormsScratchpad or a [RT] so that we can all work collaboratively 
towards well-defined evolutions?
