Literally that.
Since the development team would and will be focused at KSP2, could you give us the source code, so we might look at it and, maybe, fix some things in it to make KSP1 a better game.
I'm begging you to do it.
I have made a Kopernicus Plugin, and I know that all mods released have to include their source code. I was wondering, HOW ON EARTH (or Kerbin) CAN I MAKE A SOURCE CODE DOWNLOAD IF ALL I DID WAS TYPE PLANETARY INFORMTION INTO NOTEPAD++?
