I understand it's not system wide, and I agree with making it not dim, but I still ask that you leave an option in a settings menu somewhere to disable/enable the non-dimming - it's always a good idea to leave as many choices as possible to the end users. I might want the screen to stay on while I play, and you might want the same thing, and 99% of the people may prefer the same thing, but there's always going to be that one odd rare fella who prefers to let the screen auto-dim. Now, if it's difficult to implement making it a choice, then I agree, not-dimming gets priority.
Anyway, my WiFi started working better, so installing now. (It's showing up in FApMan btw, just not with an icon, if you intended it to have one.)
