Those who plan to use these caps for QFR, what's the plan for LED light keys? Simply cover them up or some how make a cut?
I'll probably either drill a small hole in the side, or just not worry about it. Caps lock is the only state key that really matters on a TKL, and it's quite obvious what the state is as soon as you start typing anything.
Edit: there is the Win lockout key too, which could be important for gaming. I never use it myself, but if I did I'd probably see if the light is visible without a window, and if not drill it.
