A few days ago leaked through the XDA forums one of the latest firmware for the Samsung Galaxy S3. It was the ROM XXELK4 based on Android 4.1.2 Jelly Bean that despite in testing phase proved to be stable enough to use it on a daily basis.
Among the changes in this new version is the ability to customize the notification drawer, Multi-View panel that is on the Galaxy Note 2, the possibility of using the keyboard as Swipe or the keyboard of Android 4.2, a sidebar that stands for application dock and a new application called Paper Artist.
Also this firmware comes pre rooted, so you can skip this step in case you need to install a custom ROM or some app that requires it.
