While doing the planet mini game I found it extremely annoying when I was clicking the asteroids I did not want I would often click on one of the other asteroid belts in the background. This resulted in a popup with information about that asteroid belt which hindered my ability to click the asteroids. Is this a feature that is wanted or something that could be removed?

It is something that could be removed. I'll try and come up with some way to disable asteroid belt selection while near an Accretion that doesn't feel unnatural.
