Indicator Lights / Bottleneck

Not certain if this is already a feature but I wasn't able to find anything about it in the documentation/forums. Here's the best example I can give of what I'm referring to.

Really simple in concept but super helpful.
Just an easier way to identify machines that are input-starved.
I felt the need for this primarily when using the assembly workshops because there's no animation that indicates if the workshops are functioning at all. I found myself constantly checking each workshop individually to see if they were input. I understand that the graph at the right of the screen kind of does this, but this would be a great visual reference to see where a problem exists.
Satisfactory also has these similar lights as part of the vanilla game.

Nothing grandiose, just indicator lights.

It's beginning to get tedious to go back through every machine in a complex production chain (like 3 part distillation w/ strippers and scrubbers for example) again and again to check that nothing has backed up or I missed a connector etc. Seeing at a glance where something isn't running efficiently would be a godsend.

Yes the Bottleneck mod is great.
