Make center of rotation coordinates easier to set
This issue was created automatically from an original Mantis Issue. Further discussion may take place here.
Right now, if you want to enter coordinates for the center of rotation, you have to go to Edit -> Settings -> Annotation, then click Use Custom Center and finally enter the coordinates. That is a long way away.
Let's move this a bit closer. Either have a toolbar button that pops up entry fields for setting it (like PV 2) or add it to the Adjust Camera settings that are available with one click.
