no don't think that will be possible, then we are talking about the main brightness system, and if i could do that, this QBW/init.d mod, then i could just disable ALS and mod/change the 5 normal steps to what ever is needed, and then instead maybe make an app to change & customize the 5 levels.

but for now this is the only way to get proper light levels.

and heres some Q for you:
how is the fade working precisely, does it react good enough?
and how good are the colors at level 140 - 200? i really like how the screen just "shines" at that level
