Hi, I have had no chance yet to try Gleba (because I only have a MacBook right now), but I still have a question.
Is there a possibility to change the Parameters of the Star the Planet is circling? Like, for example, the Solar irradiance, the Star's luminosity and/or the Distance between the Planet and the Star?
Also, is there a way to change the axial tilt of the Planet?
I assume that those parameters would greatly affect the climate model, especially for not carbon-copies of Earth, but I also assume that implementing those parameters as changeable is a great deal of work and therefore don't want to assume it is (already) implemented. 
Have a nice day ^^
