I find this to be a pervasive problem with Bethesda games starting a few years after The Elder Scrolls 3 Morrowind was released. They pack an insane amount of complexity into their games then provide utterly feeble tools to manage it or refuse to invest time into them as that complexity grows from game to game (especially their inventory system which hasn't changed much since Oblivion). Nothing demonstrates this better than Fallout 4's base building mechanic which is leagues better (and more complicated) than in any other game I've played. You can literally build a downtown Sanctuary with a dozen 10 story tall skyscrapers with farmland and electrical infrastructure but doing so using the Workshop as it is now (months before the release of the official game editor) is absolutely maddening and down right impractical. No 2d map or overhead camera, no alignment with complex terrain like building foundations, no templating, zero interface to manage the settlers (the current community concensus is to give each settler a different hat or outfit for each available job!), and it's just down right Unintuitive in every way. The mechanic overall feels like it was part of the game design from day 1 but the interface they give you to use it was made in a weekend.

Bethesda knows their games are bought for replayability and community mods so it seems that they make a lot of sacrifices no other gaming company would, knowing that the more annoying it is the faster some modder will totally replace it with far superior execution. To be fair though, no other company cranks out fantastic open world games that are as good as Bethesda's on such a regular basis. All of this pays off when a five year old game has graphics as good as a newly released one except with half a decade of damn near professional effort by thousands of modders.

I completely agree and want these features, but I think Bethesda is faced with the issue of overcomplicating the UI for a more mainstream audience which they're obviously hoping to attract. The UI is probably already completely overwhelming for a lot of mainstream users. At some point, I'm sure adding more options, buttons, commands, and screens might make a lot of people really uncomfortable.

Obviously though there's a balancing act at play. The flip side to not having these features is that some of the inventory management stuff is a bit inconvenient and boring and cumbersome. But people tolerate that to an extent if the rest of the experience is worthwhile.

I can't help but think Bethesda takes a "World of Warcraft" approach to UI - since no level of customization will make everyone happy, they just implement a baseline and leave the rest up to modders. (And since this only applies to desktop, the baseline works out heavily tailored to consoles.)

Of course this would work more smoothly in practice if the modding tools were ready, and if UI extensions were easy to make and manage.
