I have done it!
I have successfully written a script ("Precise adjust mask.cs") which enables you to precisely position your mask's center point by zooming into the preview window! As far as I know this has never been done before. More versions (for other things than mask center points) are to follow.
But why is this important?
Until now it was pretty difficult to properly position the center points of the individual masks pixel perfect and also magnifying glasses (software) are not enough. That's why I made the effort to write that script.
Please consider trying it out and giving valuable feedback.
Please credit me, if you modify and redistribute this script.
Hope you like it.
