I use a 5 button mouse all the time, I do not like this. It needs to be set on mouse 3 or 4, if 3 have the camera rotation be shift-mouse 3. Then change the arrow keys to wasd and the manual camera commands to the arrow keys so that shift is convenient. I'm an fps player, fps' are designed so you can play them smoothly, using wasd, shift, space, ctrl, etc with all my right hand is very convenient and it would be nice if Glest would use these smooth controls as well.
