How can I get iTunes to show at a glance which items are already on my iPhone.
I'd like to add some new tunes to my iPhone, but find myself adding songs that are already on the device. I start looking through my collection, but I can't see what's already on my iPhone. I'd like to be able to see what's not currently synced to my phone, so I can focus on adding them.
On my Zune, all synced items were marked with a little icon so you could see if it was already on the device. Like so:
The only place where summary information of what has synced is this following screen. (But obviously, it's a really ugly and unpleasant way to browse your music!)
