A fantastic post by `brentcas` in *The Verge* forums ((Still the place to find the best content on *The Verge*.)) rethinking the app switcher in iOS. I don’t like all of the concepts that he introduces (such as clear all apps), but I think what he shows *is* a better app switcher.
For starters I like the idea of two dedicated pages, one for settings and another for music, that show page specific controls below the menubar. The double-tap home button is massively convenient, but right now I think Apple is limiting its usefulness too much.
