I love the difficulty brought about by the drift issues. Don't change that. Everybody needs to simply remember lots of hand-holds like they have on the ISS. But what's frustrating is when I grab a part from a pallet of parts that I just sent up and none of the nearby nodes light up for me to connect it to. Not a huge deal for parts that allow you to place them anywhere like beams and large panels. But when I grab a docking port Sr., I need the nearby nodes to light up. If they don't, my only choice is to let it drift away as space junk and grab another one hoping this one will work. Not good. Yes, orbital construction should be an extreme challenge, but not because of glitches. By the way, don't ever put undo into EVA construction. If we need undo, we can build it in the VAB/SPH and launch it like normal.
