Have to agree that the interface design, while understandably simple in its conception, is anything but intuitive, with no tutorials or explanation on how it is intended to be used. The combination of 'Take All' and 'POV change' being both bound to 'R' means that every time you loot a container, your POV changes. Idiotic.
This interface is clearly (I mean, 100%) designed for controllers, not mouse + keyboard. Very sad.
The game looks great, though. Hopefully, the UI is still salvageable through mods.
