A settings menu with different Sansar Client options would be nice.
I would really like to see a panel where keybindings could be customized.
Windows that can be moved, undocked, and resized would be nice.
An option to change the behavior of the mouse to switch between two settings:
1) have everything work the way it currently does.
2) press ctrl or alt as a toggle switch, so the mouse cursor disappears and will allow the camera angle to be changed by moving the mouse until the ctrl or alt key is pressed again. (This would prevent people from being required to hold down right click the entire time as they walk around)
