If you consider the size of list of improvements (already suggested!) ... it's hard to resist to push for some particular one, when you see the devs listening quite directly to feedback. I'm sure Scawen will prune this reasonably. Also I hope he does check the improvements list from time to time, like once per he finish some feature (like tyre physics). Then again that list is huuuuge, must take a whole day just to read through it?
