That would be harder to do as in -als I just edited the levels & values (data) but in -simple, as you can remember, there's the algorithm that's different.
Why do you want -simple to have other 5 levels, if you don't mind me asking?
I thought the edited -als already has the levels you need. I think the only difference between these two is that -simple has fixed levels (at 20% intervals) whereas -als flexes according to ambience. Now the edited -als has fixed brightness for levels 2 to 5. THe only one that's still flexible is level 1, and that's because I use my phone a lot as bicycle mounted GPS and find it useless to be backlit in daylight.
Anyway, let me know what you think. It's not hard to make another, personalized -als - a 5 minute job, actually
