I'd argue the exact opposite, as the typical panel consisted of undifferentiated rows of unmarked buttons. Surely any sort of functionality for that interface would have to be user-defined - with the user deciding what function he or she wanted a specific button to execute, and setting the color (and perhaps the invisibly tiny labeling) to reflect that function.
User-defined, yes. Easily re-programmable, I don't think so. Unlike a simple software re-map, the TOS panels required someone on the back end linking them to the task needed. Scotty had to do some behind the scenes switching around of the warp and impulse control systems and also the impulse detonator in "The Doomsday Machine". Now a panel tasked to be the helm controls might be reconfigurable for helm controls (like inverted manual flying) but it may not be a simple push a button and make it the life support controls panel (unless it was already designed, built and wired in that way), IMHO.
