That ROM is Slim Kat ROM. Also, Slim Kat ROM has a great set of navigation controls (in fact nearly unlimited) including customizable Power Menu, Hardware buttons (up to 9 shortcuts), Navigation bar, and SlimPIE Controls. Navigation shortcuts certainly come in handy and are one of the main reasons why people install custom ROMs in the first place.
Upgrading to a new version is also easy with SlimCenter, found in your Settings menu. Slim Team has done a terrific job of bringing their core focus to Note 2 and Android 4.4.2 KitKat.
Overall, I really like Slim Kat ROM not because of its features but it’s really buttery-smooth and fast without any overclocking/tweaking. While it’s not feature-packed, that itself makes it more stable and less bloated with stuff you really don’t need.
So, definitely give this “slim” ROM a try if you haven’t and do let me know what you think!
