Advanced server icon moving

A common feature that I think should be improved is the Change Icon button on the overview. I normally find it very difficult to centre something. A crosshair or even a centre button. Advanced zooming, rotations, ect. This would help me a lot with moving icons and a lot of other people since I change my server icon fairly regularly.

Another idea would be server icon history that would be a permission if roles/members could see. However only the admins would be allowed to download them. This would help for people who may have accidentally deleted the server icon/can't find it on their computer.
