I wouldn't play with settlements just yet - wait for the hotfix patch. I (and many others) have hit showstopping bugs both with current settlements and the new autophage settlements. e.g.

• No Overseers office
• Missing settlement terminals
• Settlements with no inhabitants
• Autophage settlements missing roofs and other structures
• The new autophage items missing textures or looking low res
• Settlement event countdown timers running out but does not complete or trigger new event
• Cannot add materials to constructions projects
