Give players the ability to scale cliffs without rope! I find it quite silly that every time I want to get up a straight cliff, I always have to use a rope (or several), use space-age propulsion technology, or the matter manipulator to get up. Just let players grab cliffs and pull themselves up. Unless that's too much spritework. In that case, let us toss ropes over a cliff instead of straight at it, so that I don't attach 50 ropes to the side of a cliff instead of the top. I'd still prefer pulling myself up by hand, because it would make exploration just that much more engaging. But arcing rope tosses would still be convenient.
