Hotbars that *constantly* add and remove icons, even when *locked*, because abilities aren't left on the bar if you unequip their item/etc. Which is *extremely* annoying for radial bar usage.
I set up a real nice radial hotbar w/ my main buttons. It's the one I use the most, so I pick the wheel that the interface opens up on every time, which is, for some reason, the left-most wheel of the default unremovable 3. To add more wheels, there's a prompt when focused on either of the outer wheels. If adding a wheel on the left, the wheel is added to the far left of the stack, at the end. If added to the right, however... It appears between the right-most wheel and the center wheel. At the left-most position before the center wheel. What the fuck.
To add insult to injury, once any number of additional wheels are added, the originally-established left-most wheel is no longer the first opened - the game either continues to prioritise the actual left-most wheel if you add wheels to the left side of the radial menu, OR, if you add any to the right side, the game suddenly remembers it's supposed to be opening on the original, unmarked center wheel, only detectable by the fact that it disallows both add and remove wheel options in its context menu. Juicy fuckin' crust, that's sloppy. And it gets worse.
Once configured, there's no way to move a configured wheel left or right among the other wheels. No way to copy a wheel, duplicate it, or affect it in any way. Can't even remove a specific wheel unless it's devoid of buttons! So if you add a new wheel and it pushes your current setup out of wheel-order, well, fuck your muscle memory! EVEN worse still, when attempting to alter a button on a wheel, you have to RS in the direction of the button, and hit the face button to bring up the context menu, then select the top most option, 'Set button', or whatever the exact text is. When the menu appears, it instantly takes input from the RS, and starts wildly scrolling, so you have to stop holding the stick, pause to see if your menu selection moved anyway, move back if need be, then proceed, only to likely have to scroll down 30 tiles to find the one ability you want to add; rinse and repeat ~6-8 times on each 12-button wheel (some angles don't scroll, obvs), for up to... I counted 30 wheels before the UI started to struggle. Where's my quasi-infinite amount of regular hotbars...
Also? Wheels (and bars for that matter) should be lockable in a way that prevents any ability add/removal, whether by me or the game. I swap equipment regularly, sometimes between items/sets; my hotbars get fucked real quick. Not to mention, every time I level up, it fucks with all my prepared spells, and re-adds a bunch of abilities I intentionally removed, whether or not I've got it locked.
Give me a setting to leave abilities where they are, whether I qualify to use them or not at that point in time, and just grey them out. I'd rather get my wheels/bars set up once, for all the equipment I'm using, than constantly having to tweak/retweak them.
Especially when tweaking them re: radial menus is as clunky and unforgiving as it is right now.
Which is a shame, b/c radial menus are what makes many-button games like CRPGs work in handheld. I played Underrail on Steam - a great little isometric post-apoc metro-style RPG, reminiscent of the early Fallouts - and I played it entirely with my Steam Controller, b/c Steam Input allows you to make completely custom radial menus of whatever the hell inputs you want, including pre-set combos, keybinds, combo binds, program launches, and pretty much anything else. They can nest, they can have multiple functions on doubletap/longpress/swipe-and-release, and the trackpad's haptics meant I could feel each button as I passed over it, which aided HUGELY in making them smooth as hell.
And all I did for Underrail was bind like four or so 12 button wheels to 0-9, Shift+0-9, Ctrl+0-9, C+S+0-9, and then I just filled out the game's provided hotbars and keybound them as desired. Given each radial was just a number pad in the shape of a clock, it became second nature to input desired keybinds at, or even better than, keyboard.
BG3 is very close to that, but its current customization controls for radials are hot garbage. Praying for improvements, or better yet, mods.
If you read this far, you're amazing, and you should send me an anonymous ask with a nice image example of your favourite kind of eroticized genitals - I am not asking for yours, to be clear, unless yours are your favourite kind, then, well, go ahead! We're in the deep chost down here, I can be as lewd as I like!
Anyway. That's all. Lol.
