iOS 5 Feature Request

Although there are still plenty of things I'd like to see done on iOS, one in particular just came to mind while flipping through pages of my apps.  I know you can double-click the home button to reveal the suspended (recently used) apps, however I think it'd be nice to have a mode you could turn on that would put all of your most recently used apps on the first page and then apps you haven't used in a while on the other pages with the apps you use the least on the last possible page.  

I understand this could be confusing for some considering your apps would move around quite often on the first page, but maybe they don't have to.  Maybe they only move if they are going to the 2nd page and so on.  If your app is in the top 16 most used apps, it stays on the first page and in the same order.  If it gets bumped beyond that, then they would be in whatever order they rank on pages further down.  

What are your thoughts on this method?  Does the "suspended apps" dock area meet this same type of need?
