I kind of agree with Jordan, to a degree. Removing clutter is great, as I used to add 2 null shaders, one inside the other to invisibly link to a compute terrain or compute normal (indeed off some sideline or loose fractal), to get rid of all the lines, and have it off the main nodes anyway. So this is very handy.
But you now may have loose shaders that 'carry' the pops, and are not distinguishable, and seem redundant. But I don't think that can be changed within the software, unless there can be a way to set a color to the node manually (or lock it?). I usually add a group around it with big letters saying KEEP!, or something like that.
