Is there any chance of a new third-person mouselook control scheme?
Perhaps allowing us to enter third-person mouselook by clicking the back of our avatar heads and holding for 5 seconds to lock it in place so we don't have to hold the left mouse button at all times to use this feature.
Of course, switching to and from TPS mouselook with a key would be great as well. As would being able to control the right-click menu and activate objects by left-clicking what is under a crosshair.
Of course, these requests are secondary to the actual control scheme change and are really more of just icing on the cake than anything.
