I'm wondering if there's a way to make a modification to the chance of planets being habitable. Right now the "Abundant" setting is a bit misleading; habitable planets seem to be around a 30% chance on "Abundant", and it only goes downhill from there. I'd prefer a setup that's something along the lines of systems having an average of two planets and about half of planets being habitable, but it seems that the system generates lots of planets (even under "Occasional") but not enough habitable ones (under "Abundant"). Any suggestions?
