Ya I've used that island for a while now, never sent any settlers there though. Just build like 150 turrets and left it for now.
I knew I can put bobbleheads on display, but comics you find?
They can be displayed too. With racks buildable in furniture-shelves.
Wat saddens me is that displaying any of these doesn't affect happyness in the settlement.
Hopefully someone discovers how to display mr. handy and sentribot models. Also the buttercup toy quest reward.
Not all of my settlements have 21 people. Only those where I put the recruitment tower. Others are either empty or hold only default "family".
The population growth everywhere I planned for after beating the main quest, not before.
While I made all populated settlements selfsufficient, the better option is to connect them all and turn one or two settlements into food processing. Sanctuary can be turned into water processing and distribute it to all other settlements.
I don't have any settler in Boston Airport - it's concrete and one can't grow plants there. I didn't find if it's possible to build planters (mutfruit planter provides two food, jot just one) so the only option for such places is provisionist routes.
Building trading stations just about everywhere to earn caps passively I'd say no, it's not worth it. If it's caps you need, you can make it by selling tons of purified water accessible in Sanctuary. Means, build traders only in Sanctuary.
Or if you find another place where you can "plant" dozens of huge water purifiers.
And of course scavenging station so water surplus gets stored in the workbench.
