Assuming that alex will go through all the sub menus this brings up.
The interface and UI options are many and varied! Menus within menus within menus.
You have options for UI window colours (including Gamer™️ RGB rainbow effects), the opacity (for that cool translucent effect), the brightness, the size, the width or height, the position. You have options for notifications windows that are mostly the same, color size etc. Options for your main menu, your inventory, your map (both full size and mini), achievements, notes, quests, perks, status, party tab, skills and a general set of options for ‘other’.
As well as options on how to display all those things, theres options on how to interact with them. You can set your menus to be voice activated, touch activated, you can record gestures for it, you can set it to work with subvocalisation or eye movements, you can record and add non standard inputs if none of those are to your liking.
You can change how much of your UI is displayed at any time and under what conditions. A lot of resource meters and timers are currently set to not show unless they are actually being used, and theres tons of them. You can change if you want to display your Mana bar, your hunger meter, tiredness, how irradiated you are, if you are poisoned, if you are enchanted, dazed, hypnotised, enthralled or ‘charmed’ (wich has a pink heart symbol as its icon), and a dozen other obscure status effects. You can change how your party UI is displayed, what parts of their status should be shown and under what conditions. Can even go deeper into the options and change how long it takes for an unused UI widget to fade when not being used, or wether it should always be showing if beyond a certain thresh-hold (like say always showing the health bar when under 40% health).
There’s UI widgets unrelated to your normal menus and status that have options for them, a clock, a compass, a greyed out option for a music player, a thermometer, a barometer, and other widget icons that aren’t obvious what they are for. And each of those widgets has the same levels of customisation as all the UI and status displays.
However you want your information displayed or interacted with, there is probably an option to enable that.
Current UI settings are to always show health and stamina, and situationally hide everything else until it becomes relevant. Settings for interacting with menus are currently set to voice and touch.
