I'm quite linking the auto track zoom - though I'm a bit perplexed why Folders don't auto unzoom & need to be manually resized up & down using the splitter bar. Since the only additional info shown on the folder is the track type counts maybe those should be moved to the top "line" of the folder display & they could stay unzoomed.
Also, with autozoom turned on, once you select on a bus & it zooms there's no way to not have a bus selected/zoomed so you end up with a permanently zoomed bus stealing screen space.
Then again, these may be things associated with using XP (please, no lectures

).
