how do we organize our apps in itunes library
No - there is nothing in iTunes to make it easier. You can also use Xcode and the iPhone configuration utility to get a little more screen real estate, but managing apps is still fairly simplistic. The configuration utility does make it possible to automate installing several apps, so that's a step in the right direction for some.

I've filed bugs and sent feedback to Apple asking for more screen real-estate in iTunes to start making app management easier.


They have a 'Use Full Window for iTunes Store' view so it's not inconceivable they might do the same for iOS management at some point. Feel free to link to my picture in your bug report or feedback if you also want to ask Apple for this change.
