This concerns mainly the PC version. We've seen how many threads there are about the terrible overall UI on PC, so I won't go into detail on that. I encountered a somewhat different issue. Since the keybinds are different now compared to Oblivion and Morrowind, I changed them around to behave more like the earlier games since it's just how my mindset is when playing an Elder Scrolls game. The issue is that that the tooltips displaying the keybinds will only sometimes reflect the changes I made, which leads to a lot of confusion and frustration. Since I switched around the sheathe and third person keys for example, the commands using the same keys in my inventory didn't have their tooltips changed, so if the game tells me that this button is for favoriting an item, it's in fact for throwing it away.
There's several instances of this all over the place, while in other cases the tooltips did appear to notice my changes, such as for speaking with NPCs or activating objects.

I mean, really, how does this type of stuff pass QA?
