I am slowly starting to understand a few things, but a documentation will definitely be useful 
The thing that puzzles me most is the manipulator concept!
- While the mode selection keys (F2, etc) work fine, it seems I can't get the tool keys (1, 2, etc) to work. Can be related to my French keyboard layout... Tried with main keyboard digit keys, shift+digit keys and numeric keypad. Nothing work.
- Though I have period ('.') defined as decimal separator on my system, windows with numerical fields (such as snapping grid window) display numbers with a comma and want a comma as decimal separator on input (very clumsy with numerical keypad...)
- primitives icons are quite illegible
