In the release notes for 5.1.70:
The saved view offset is now restored correctly when opening an existing project, so the view is restored at the place you were last working (Windows only).
I am compelled to say this is a really good feature. I was always frustrated by having to scroll through pages or ‘goto page’ to get to where I was last working - if I could even remember the spot.
This is a lovely breath of fresh air. Thank you.
