I think that using one control for both status leds (which is what we are
usually
talking about) and illuminator(s) is a bad idea. I'm fine with standardizing
these,
but can we please have 2 CID's one for status lights and one for the led. Esp,
as I
can easily see us supporting a microscope in the future where the microscope
itself
or other devices with the same bridge will have a status led, so then we will
need
2 separate controls anyways.
Regards,
Hans
