Well, I would need something that looks simple at first glance, but would be very usefull for big scenes. I like doing large exterior scenes and I often have a surface equal to 4 times my 16/9 screen full of nodes. I would like the ability of applying a chosen color to the nodes in order to not waste time searching nodes : for example i could apply a green color to nodes relative to Vegetation, a grey color for Buildings, a Blue color for Cars...

Also, when clicking on a material or texture in the Nodes Inspector, it would be usefull to get the corresponding pins enlighted ( for example in visible bright red color) in the Node editor to see quickly which objects are sharing these materials or textures.
