I have an idea for some simple modifications to the keyboard backlight options for keyboards such as the MX mechanical and similar models.

Why not introduce linear combinations of existing presents? Such as 50% static + 50% reactive, for instance. In this example, the keyboard's backlight would be always on dimly, and then react to each keypress by locally getting brighter.

Going further, why not allow the user to define their own keyboard backlight patterns/ algorithms via logi options+?

These ideas would probably only require updating software or firmware, so existing hardware could benefit from the improvements.
