I totally expect this kind of things to be possible.
I want to give access to the project manager, projects... the file.defines 
part will need a bit more time, I definitely would like to give access to the 
AST, I just don't know how (well, from a C++ point of view, I can find, it's 
jsut the interface).

Giving access to the "Find Usage" method should give you all that.

I don't see why not. Definitely something I want to do.

On another subject, I wonder if javascript is the right choice, maybe QML 
would be nice, for 2 reasons:
 * support of QtScript in Qt 5.0
 * you can still do some javascripts
 * it opens the door to awesomeness
At the same time, those scripts will be by nature imperative... I have this 
idea in my mind for some time now, I need to experiment. I probably need an 
example to convince myself.
