I remember in the old versions of Calibre the view had some page flip animation where it would slide, however I can't find anyway to turn that on in the new version of the viewer.
If this is no longer a feature, how can I downgrade just the viewer?

Edit: I looked into the older versions and it's right there under "Page Flip/ Scrolling options". Is that gone in 5.20? Also where have "Themes" moved too, because that's a feature missing in the new viewer as well.
