One of my favorite ROMs for Note 1 is now available for your rooted Galaxy Note 2 GT-N7100. The developer of Crash ROM has made his new ROM available for the Note 2.
Although in its initial stages and just version 1 for now, it does come with many useful features you will appreciate. Off the bat, the Crash ROM comes with Battery Spy and Light Manager. Light Manager can easily customize the LED notifications to the colors you desire per app basis.
