Let the user color the node

About the color. I don´t mean to color the whole node :D(man, that would be kindergarden style)
I mean a small corner, area, indicator or whatever inside the node. Shape could be rectangular, dot, triangle...and and and.

So you can let the user descide to color his nodes, if he want. This is just a visual categorizing ! (not only via text)
