If we speak about interface woes, one of most woeful things is inability to switch weapons/equipment via hotkey. It would be logical to equip mag amps when I switch to magic part of bar, and then it could be handy to switch to sword when I'm changed shortcut bar to another one, filled with melee actions. Yet, there is no any way to switch weapon (and preferrably other equipment) via hotkeys, as far as I figured out. This is really strange, granted how convenient action toolbar switching happens.
