It would be great to have these two feature incorporated. I have a microstation background and I used these all the time.
Rotate view to view at different angles, obviously, and you could do a 'rotate view element' which rotates the view so that an element you select appears at angle 0 (horizontal in the case of a line). Say you're printing a plan sheet that's not at an even angle...
Modify element to easily move the end of a line segment from one location to another. QCAD has the stretch tool which can kind of do that but that's usually too complex for just adjusting a line segment end.
Also I'm looking forward to obtaining user input (x, y coords) for the scripting language. I read hear somewhere that that's not available in 2.x but hopefully in 3.0.
