-fix the bugged action point consumption when in cast sequence and another skill is selected
-more hotkey slots and/or hotkeys for switching (as suggested shift + number or shift + mouse wheel)
-save position of windows (inventory, chat window,etc.) and group formation
-pause in single player (in esc menu)
-dex weapons with crushing (e.g. blackjack is more of a dex than str weapon) and slashing (e.g. whip?)
-little arrow on enemy ground circles; sometimes hard to tell where the back is (and i like my daggers in the back)
