I've recently received a Corsair Katar mouse as a gift, and I've downloaded the CUE to program in a simple lighting effect (50%-75% brightness wave over 4s + 100% on click). I'm a big fan of the ability to set different DPI profiles and to switch between them so quickly, but I would like an option to add an indicator that would tell me which mode I've just changed into. It would pop up in a preconfigured location on the screen (either one of the corners, or set by a drag-n-drop interface). It would show up immediately, wait for a configurable amount of time, and then (optionally) fade out over a short interval, like 0.3s. The size, font/background color, and opacity of the indicator should each be configurable. Ingame I envision that it would end up looking something like this:
