<space> to scroll down in a pdf document that does not fit completely in a frame. However, this disrupts the reading flow as I need to find again the correct line that is now repositioned to show the bottom part of the pdf.
I would like to have a scrolling indicator as illustrated in the second screenshot below. Is someone aware if such a feature already exists for emacs?
Update: There are two work-in-progress patches in pdf-tools that would solve this issue. Unfortunately, they seem to be abandoned.
