I've currently got around 700 apps installed on my desktop PC, and 500 installed on my iPad.
I'm trying to remove all of the apps from my iTunes library that aren't on my PC, but it seems the only way of doing this is to delete my entire library and sync them back across which I have to be honest and say I'm not very keen on. It's a nightmare to have to keep clicking between them, especially in the new iTunes. At the moment I'm taking a screenshot every time I delete an app, which is far from ideal.
I'm wondering if there is a way to have one window open with a list of apps, and one window open with a list of my syncs within iTunes?
