Some bad news for those of you who missed that sense of organization missing from Android. Larva Labs, the developers behind SlideScreen, have decided to shut the SlideScreen project down after recent updates to the Gmail application. In the update, Google intentionally restricted access to the application's data. This is likely a security move in light of all of the malicious malware attacks as of late.
SlideScreen needed access to that data to show users' emails on the alternate homescreen. SlideScreen was one of the first desktop replacements for Android and it did more than mimic or build upon the default launcher.
