Keyboard backlight control - potential solution

I've created a thread on reddit but probably the audience here is more appropriate.

It basically emulates how a normal kb backlight behaves (i.e. Mac), shutting it down on some configurable idle time and waking it up on key press/mouse move.
Could possibly work with other models as well, but only tested with X230.
My reverse engineering skills are pretty limited so I had to piggyback on the existing Lenovo app (Win10), since I couldn't figure out how it actually controls the backlight.

Drop both into the same directory. Edit the script file to suit your needs. You need AutoHotKey installed, I can also make an executable, but this is not a final package.

Oh wow, flashing keyboard lights for Christmas

Please let us know progress as we would be interested in this; our X230 would eventually be upgraded to Win10 (again) in a few years time!

I don't think I will continue developing this as it serves the purpose just fine. I will release the project on github, at a later time, after the bugs have been ironed out.
I've been trying to recruit developers and REs on this topic for months now, so I've decided to finally spend a night and figure everything out. My only conclusion is that: a) couldn't find anyone interested or b) couldn't find anyone capable. In either case, releasing the source code seems kind of pointless...

Interesting little application.

During your development, did you tinker with brightness levels of the backlight? I've been looking for something that would add a third, brighter level without degrading (too much) the lifespan of the white LED array under the keyboard.

Well, I think the values are somehow hard-coded, as in hardware. Even the fade in/out seems hardcoded as it behaves the same without an OS running.
You can get download the exe file and try different values, but I've seen none that work, apart from 0,1 and 2. I thought 3 would turn on the thinklight, but it did not happen.
