I think I have another point for the wish list - I wish that roof design in addition to what can be done today - is more like wall design.
For example:
1) How to put OSB boards on the roof?
2) How to put items that are not rafters but you want to put battens manually?
What I mean is that roof design seems not to be as flexible as it could be. Maybe later I will show a picture of what I want to do, but I have to do it with rafters.
