I get that there is an art style that they are trying to go for here, but I agree. Was trying to make a node earlier to Duna. I had 2 vessels in orbit of Kerbin, and when trying to make the node, I found myself mis-clicking on the other craft because the icon was so large even when I was zoomed all the way out. It should, like in the first game, almost prioritize the node and scale the other icons down.
