Hi Squinge,
I have sort of an odd list- I don't know if others would find useful but these would be essential for movie makers. I don't expect you to make all of these but the first one is probably what I'd personally like to see most:
Seasons
No butterflies or fireflies (weird request but they are weird on my urban sets)
No falling during skating for high skill (or at all)
General
No progress bar on instruments, karaoke machine, do homework
Any one of these would be greatly appreciated, especially the first one. Thanks for your consideration and your time.
