Default Adjust Autobrightness + LED Notification Control


I know there has been some talking about it but I have the following questions:

1.) I really love the DroidKang feauture of customizing autobrightness settings and notification led. Which ROMs has the same feauture?

2.) I can't live without Cataclysm's "Immersive mode" and "hide nav buttons" (shortcuts on TILES layout)

So the question is: How to bring those 2 together?
Also, I'd like to know which kernels use lower brightness value? Like ElementalX does.

I know I could just try ALL of the ROMS and all of the Kernels, but I just can't do that. SO suggestions are MORE than welcome
