Minor issue I noticed. There appears to be some typos in the mining tooltip.
Mining command, Line 40:
checkBox.tooltip = "Determines wether all asteroids in a sector (checkded), \nor only resource asteroids (unchecked) will be mined."
It should read:
checkBox.tooltip = "Determines whether all asteroids in a sector (checked), \nor only resource asteroids (unchecked) will be mined."
