The only thing I want is for the iOS grid system for apps to be overhauled or discarded altogether.
Organizing apps on home pages by purpose/type is tedious and, ultimately, pointless. The next time you install a new app, you're likely to have them all get bumped to the next page.
Muscle memory? Forget about it. Everything is in a different place in landscape or portrait orientation.
The grid system, by and large, hasn't changed since OS 1.0. Sure, they added multiple home screens, folders, and the ability to reorganize apps. But these are all responses to the inadequacy of the rigid app organization.
I just want to have a single place where I have all my magazines and news apps, one place for sys admin and monitoring tools, and the rest, and not have to constantly be futzing with it. Folders are okay, but things in folders tend to be lost to me.
