In Mathematica 7 for Windows, is it possible to use custom GUI magnifications?
I am able to use a custom Magnification by setting Magnification->1.05 in my Notebook options. The FrontEnd only displays 1.0 1.25 1.5 etc. So if I switch once, I cannot go back without editing the file by hand.
Is there a way to modify the Magnification menu such as to include other (finer) values like 1.05, 1.10, 1.16, 1.33 ?
