This is really such a little thing, but if Skyrim improved on this it would make harvesting so much easier. Harvesting from plants for alchemy was never much of a problem, except when it came to plants like wisp stalks. They were slender and kinda difficult to target with your cursor. Of course, it only took about a second longer to actually be able to aim your cursor and target them, but when you're in a cave and there are dozens you are kinda absent-mindedly collecting as you run through the dungeon, it can kind of get a little bit bothersome. Really I'm thinking how much easier it would be if the alchemical plants' targeting area was just a little more within their general area instead of the precision it required in Oblivion. Again, it was only a problem sometimes, because usually the plants themselves were big and easy to harvest, but I do hope Skyrim improves this.
