It's possible the WiiM wizards will be able to create some settings that would enable users to set the LED to do any number of things. Personally, I think it would be most helpful to have it change color in accordance with the bit depth and sample rate of what's playing, and to emit a faint glow when it's powered up, and dark when off. And offhand, I can think of at least a dozen other options, some useful, some not.
