I just ran into a bug which I quite common in Pd, and thought of a simple, graphical way to show status which would make such bugs trivial to spot. Basically, I had a [+ 17] which I had mistakenly input data on the right inlet. I then was debugging the logic since I thought the [+ 17] was adding 17.
So I was thinking that whenever an argument is overridden by data on an inlet, the argument should change color to clearly display that that argument is no longer in effect.
Right now Pd is very black-and-white, and I support not adding extraneous colors. But I think that we should be using color to show things, and this is a simple example where I think it makes sense.

If nature has made any one thing less susceptible than all others of exclusive property, it is the action of the thinking power called an idea, which an individual may exclusively possess as long as he keeps it to himself; but the moment it is divulged, it forces itself into the possession of everyone, and the receiver cannot dispossess himself of it. - Thomas Jefferson
