This mod is great if you have a lot of colonists and want to some of them to found a new colony, to be able to devote your full attention to that colony you can unload your other colonies and play on the new one, need help with some raid or with resources during a toxic fallout? Just load the maps you previously unloaded and send help. Need something from that colony? No problem, load it again and play like nothing happened. This mod lets you unload('freeze') any colony so you can focus on your other colonies.
You have to many colonies and its getting harder day by day to manage all of them? Have you ever wanted to build a strong faction and to control large amounts of land like normal factions do but you could not manage more than some colonies at a time? Then this mod is for you.
