Do developers have the ability to specify whether or not app data is included with the regular iTunes backup? And do they have the abili to include a setting within their apps to let the user decide if they want the app data included in backups? I have a number of comics I've bought from the Comixology and Marvel apps, and it since I can download them at any time it would be nice to not have them included in my regular iTunes backups and causing the backups to be larger and take longer. The same holds true for video playing apps like Buzz Player. The files can be so large that it would be nice if I could select to not have the files included in backups.
