Hiding an app was a big part of the Blur overhead, or least some part of it. So you really want Motorola to build more on top of the current (fairly clean ICS) look and feel just so you can hide apps, when the apps really are not hidden but just placed in another folder? At least this way of disabling an app will stop you from getting updates for those apps. I like this way a lot better then just hiding an app.
No. I have not installed any updates, and it doesn't even appear under manage apps. Very strange.
Are you sure you're looking under "All", and not "Downloaded"? If you haven't installed any updates, then it might only show up under "All" in Manage apps. Once you install an update, then it also shows up under "Downloaded."
