I just had an nice idea. To my knowledge, there is no such feature in US2, but I'd like to have the ability to create Blank Planets and Stars. For example, you go Objects and click "Create Blank Planet". It would then open up a window where you would fill in the information, like its name, size, mass, elemental composition, atmosphere data, magnetic field etc. This would make things a lot easier, because you would no longer have to pick a existing planet, rename it and adjust it to your liking, not to mention modifying the files to give it atmosphere etc.
Just a thought. Your opinions?
