Allow for manual page offset in double page view
The offset page toggle does not always work and most of the time the pages end up mismatched.
Is there a possibility to add a way to force a certain offset?
A solution can be to allow the user to move by one page, using the progress bar preview, thus fixing the offset issue, i.e. instead of moving from 2/3 to 4/5, you move from 2/3 to 3/4 thus the offset is fixed.
