In KSP, you can control one Kerbal at a time and when you time wrap they just standing there starting at nothing. Funny thing is that I once left Valentina on Minmus for two whole years in her suit standing still staring at nothing.
It would be cool if you can set each Kerbal to do something, such as patrol around the base ( and maybe gain some science ) or command them to take cargo and store it in other cargo space. Cooler even if you can set it to repair anything in proximity and they just repair anything damaged. Overall, I want to see other Kerbals do something other than sitting inside the base and just standing still when you leave them.
