Chroma suggestion to a new quick effect

How about a learning effect?

Let's say we put a layer of normal effect, lets pick fire, then we have a layer that remembers, and shows, how much we use a specific button. Let's say we use 1-5 and a few buttons around WASD.

This effect we might be able to set our own colors dependent on the number of key presses and only when the game is on (Gaming mode).

The result would might be that WASD becomes red. Shift orange and the other key presses different dependent on how much we use it.

This would, not only, be useful to me when setting up a profile for the first time but also when analyzing the key placement and habits.

The function can, of course, be expanded upon with other functionality and the ability to copy this usage profile data to a completely custom profile.

If anyone else has any ideas to add, change, or if this function already exists but i have missed it, please let me know.
