forum user @knowbuddy write this neat little mod to hide the orbits in the mapview of vessels and planets. He is no longer doing KSP and was happy to have me adopt it. Original thread is here: https://forum.kerbalspaceprogram.com/index.php?/topic/159930-141-toomanyorbits-v112/
Have you launched so many vessels that Kerbin looks like the Flying Spaghetti Monster?
Setting up maneuvers is harder than it should be because there are just too many orbit lines?
