Feature request: Indicate idle devices

[7eggert]

I suggest having a yellow instead of a green indicator on powered-but-idle machines.

While it's easy to see an active oven, there is e.g. no good indication on the backside of a drill to see wheather it's drilling.

I'll add that to the to-do list, although there are some technical reasons that make it difficult to implement that on the laser drill.
