We have no arrow quivers/slot with it's own easy radial quick access click and forget icone and shortcut for it.
That way i don't have to go into inventory just to shoot an arrow every time... For some reason I have to drag it to hotbar then use it or right click and use it. The fact that i need to even go to inventory in the first place is just maddness in 2023.
Takes ages to setup and maintain even if i have all my arrows in "arrow backpack" on my hotbar. That should just be a quivers item/system that does it all automatically.
I certainly wouldn’t claim the inventory or UI couldn’t be improved, but accessing special arrows is already pretty easy, on PC at least. Simply click on the icon for your ranged weapon to the right of the character portrait and the hotbar will change to show all the available actions you can carry out with that weapon, including firing any special arrows in the current character’s inventory. I’ve never tried it, but this may not work if you put arrows in a separate container as you say you do. Personally, I prefer not to use containers and simply filter the inventory.
