It's like nobody on the team or in the beta has even played a well designed UI. Not only are you limited to 10 viewable slots but there are NO hotkeys to cycle between bars! That's not the worst of it!!! The worst is the tiny tiny little arrows you must click on to switch bars!!! How on earth can this happen?

We need more that 10 viewable slots, we should be able to add as many top layer slots as we want. There should be hotkeys to switch between multiple layers, NOT TINY LITTLE ARROWS.

Great game so far but the UI seems like an afterthought.
