When i am on a sheet , then go to a sheet detail, when i go back to the first sheet it zooms to fit page size. So the feature i am recommending is the ability to cache your zoom extents when switching sheets back and forth or to another.
Is that how bluebeam works?

Turns out zzTO already does partially what your after. Here is a 40 second vid and it works wonderful for me. LINK
I think I understand what you mean tho, any time you go to a page on the left it would remember your last zoom setting, I would not like that if I'm being real.
