I thought you made the point clear on your original post well enough. You are essentially creating a Game Center like app of some sort for "Document & Data". Well, perhaps just the Document part, but similar nevertheless.
But I stand by my earlier post that you are essentially window dressing Document & Data section of Settings app. Yes, you are adding few new interesting features such as showing badge count for each apps, AirDrop, and Safari download manager. But it is essentially just another Springboard supplement feature, joining Game Center, Newstand, and Passport. While that may appear to be the approach Apple is taking, I sincerely hope Apple will fix Springboard once and for all instead.
That's a better way of explaining it. It is very similar to Game Center, Newstand, and Passport. I see what you mean by it not being necessary, but I think it would be good if people at least had the option to use it. It has a lot more features than Documents & Data in Settings. I saw somebody's mockup of the Settings app having toggles next to each native app. It would be nice to hide certain Springboard apps if you don't use them at all. That way people could just hide the iDocuments app if they feel they don't need to use it (although I personally think it is more useful than Newstand).
This app may target a small group of users (people that want to be productive on iOS instead of use it only for consumer reasons), but I tried to make it as user friendly and marketable as possible to the general public. This could be the first step to the removal of Finder in OS X and the merging of OS X and iOS (if that ever happens). In my WWDC 2013 Concept, I put iDocuments on both OS X Lynx and iOS 7, although Finder still exists in OS X Lynx. iDocuments is just an easier way to manage files, and if file management could be made very easy, it might work on iOS.
I guess we will just have to see what Apple does in iOS 7.
