+1 for master/music/sfx volume sliders (ye I know I'm whining alrd)
+1 for quick save/load
+1 for option to remove head-bob
and some other stuff I'd like to see,
- "import default party"-button in the character editor, I wanted to go with the default party but do just some minor tweaks

- possibility to turn all the way backwards with the mouse look
- possibility to move while mouselooking, i.e. forward takes you to the direction you are (mostly) pointing at (if you are looking at a 45degree angle then it wouldn't do anything etc)
- achievements menu/tracking inside the game, so people playing also the standalone would be able to see their progress with the steam achievements, if they enjoy that sort of thing, and possibly way to copy your game state/cfg file between the versions and have steam pick up your progress
