Can we edit or create new and custom galaxies? Set how many particles/stars they have?
I tripped over some controls for editing a ring at one point, that let me set how many particles, and of course now I can't find the thing. Only in the non-steam version possibly?
Small bug report, if you use the demo to render a movie, it loses track of time and will render a simulation for hours while only a couple of minutes of pro demo time have elapsed. I used the demo to render 5000 frames.

Fun program, thank you!
