I have two suggestions:
1. Map the camera zoom setting to the menu. In native Warband, you can control camera zoom with the +/- keys on the numpad. However, your setting will not save and every time you restart the game you will have hold +/- if you want your camera to zoom in/out. It would be better if it saved.
2. Make infantry camera/actor control behave the same in singleplayer as it does in multiplayer. In singleplayer, your actor will not rotate with the camera unless you are moving, or holding an attack or block. This was fixed in multiplayer but in singleplayer it remains. The current behaviour makes it impossible for the player to turn their character when remaining still without performing an action. If the player wants to view their character's outfit, there is a view outfit button for that.
