I've read the work-around of using two windows, but sometimes I want to zoom into a particular part of my visualization and lock this part, so students can better read this part. And at the same time I might have to zoom in even more so that I can better add aspects. It would be extremely helpful to have this lock-feature again. Especially on a small screen multiple windows result in having not enough space to actually do what I want to do.
I've seen you closing this request several times, but I wanted to emphasize that the trick is good, but sometimes the zoom lock would be more convenient.
Thank you for reading my request. :-)
