Shaded Controls when not in use

I sometimes make large filters with tons of controls. I had one experimental one that had over a hundred controls. there were many pathways throughout this filter and therefore not all of the controls would work when within a given pathway. obviously, this makes adjusting settings a bit of a trick at times because in some configurations, some controls are inactive.

I don't know how hard it would be to do, but it would be fantastic if only the current pathway's controls were lit up with the rest being temporarily shaded. then finding the current working controls would be easy. when you change the pathways and new controls are now active and some that were working are now inactive, the shading on controls would change to reflect that.

thanks.
