I've tested this out on the Framework Laptop 13, 11th gen intel core
and AMD Ryzen 7040 editions.

It works fairly well! I found a couple minor issues in day-to-day use:

- Restoring the trigger to chromeos-auto does not always put the EC
back in control, e.g. the side lights no longer return to reporting
charge status.
  I believe this happens when you move from any trigger except "none"
to chromeos-auto, without first setting "none".
- The multicolor intensities report 6x 100 by default; if you set the
brightness with the intensities set as such, it becomes only red. I
would have
  expected intensities of 100 0 0 0 0 0 if that were the case

Thomas, I apologize for the duplicate message; my mail client config
here defaults to "reply" rather than "reply all."

Thanks,
Dustin
