@Michael Gibson:
sure, I will send you some examples as soon as I get home.

@Ced:
I think the biggest advantage over any other CAD software is its simplicity and speed. Its very straightforward and supereasy to learn.
From the video I think the most useful would be No.9, i.e. move/scale/rotate tool for line segments and "vertexes"

Also one major (to me)thing for the wishlist:
-loop selection by doubleclicking the edge so you can select whole loop and apply fillet instead of clicking every single curve segment

Few minor things:
-Perhaps this can be done with simple script but while holding shift, the straight snap would be automatically turned on; and turned off when shift is released
-when selecting multiple objects/lines, you would need to hold CTRL and click and removing already selected object/line would be done by holding ALT
-Sometimes its a bit annoying that when you are doing booleans , sometimes you get automatically activated some type of boolean and sometimes its not activated .
