Thanks for the reply.
Re: Auto-sync. I'm aware of that control, but the problem is - as I said - that it doesn't seem to start to auto-sync unless I go to click on the Sync Handheld control. It's a major - and dealbreaking these days - hassle to have to wait another 5 minutes when I'm on my way out because I didn't click on that when I connected the handheld.
Re: Podcast I'll keep my eye on this and do some tests by not going into Podcasts, shutting down MC after a while and seeing if I have updates. Basically the situation seems to me to be that unless I go into Podcasts, it won't start downloading new episodes.
Tree state: If users can grasp it in iTunes, I'm sure they can grasp it in MC. I'm also aware of the startup interface location but the interest is more e.g. for it to open with my nested playlists visible in the state I last left it at.
