As we know CTRL allows us to move camera to different position and lock it there on release. Second press of CTRL returns the camera back to original position. Technically you CAN move camera along with the mouse, but you have to hold CTRL to do that. Would be convinient to have a switch like CAPSLOCK to link camera to mouse like CTRL does, and release it when pressed the second time. Also there is a ZOOM option in game menu, that you can use and it changes zoom instantly, but to do so you need to make 4-5 clicks. Wouldnt it be more usefull to link this option to say, PGUP PGDOWN?
