I'm wondering if I'm missing something with settlements or if it really has been implemented as badly as it seems to be:
1) I'm not seeing a way to monitor what task each settler is assigned to and what tasks have no settlers assigned to them. This seems like such a basic and obvious thing that I'm mostly convinced that I'm just missing it somehow. Surely Bethesda wouldn't bodge the job badly enough to have tasks requiring settlers and no way to monitor it?
2) I'm not seeing a way to change perspective when building. First person is very badly suited to settlement building, so it would be an obvious choice to allow zooming out at least and preferably "god view".
3) I'm not seeing a way to change the length of stairs to ensure they line up with where you want them to go from and to.
4) I'm not seeing a way to build anything to go under a floor so it matches the level of adjoining flooring on slightly higher ground, e.g. to extend flooring off a pre-existing foundation. Nor am I seeing a way to use concrete or cement for the same purpose (or any other purpose, come to think of it).
5) I'm not seeing a way to build construction items of specific size. Anyone who could build floor, wall, ceiling and roof sections from scrap wood and/or steel should be able to build them to whatever size they require to neatly fit gaps.
Settlement building and management looks like a tagged-on afterthought to me, done as a rush job. It seems very clumsy and missing some important things, especially (1). It's not like settlement building is a new thing in games - there have been entire games of it for years. Bethesda wouldn't have had to come up with new ideas for a new type of game.
Less importantly:
6) I don't seem to be able to have settlers harvest plants I've planted. They work on them, but I'm not seeing an increase in the number in my inventory.
7) I'm not seeing an option to build a kennel for Dogmeat.
