Nice, but that only solves third problem.

but we still need to expand a bit the XAP_Frame API to give access to the
internal EV_Menu_LabelSet & EV_Menu_Layout (right now, there are no such
internal variables, we should also add them and make derived classes use
these base members instead of their platform specific variants).
Ie, with the app (that we can get easily), we can get:
1) Set of actions
2) Set of frames
And for each frame, we should get:
3) Set of labels
4) Layout
Actually we can not get 3 & 4.
