Ok, so there's already so much out there about how managing your settler's duties is not clear cut enough. I'll just say this, Why on god's not so green wasteland do my settlers not have names, or at the very least let me name them. I could for example call this guy Johnny Cornfield. Hey look at that i know iv'e assigned this guy to farm corn. Good old Johnny farming all that corn. one simple thing, just let me name them. it would be more immersive and useful.
Additionally, maybe i'm the only one but i really, really, wish there was a "dump" box somewhere in each settlement. in said box i could drop all half decent gear i'm not using and let the settlers grab bag loot as they need it. I want them to be geared up, but i'll be darned if i'm going to take the time to dress each one like a baby.
That is all. Godspeed out there in the wasteland.
