How to increase the speed of scrolling in the PDF viewer

It is too slower than other readers

This is one of my main issues as well. It seems to be images that slow it down most. I have a lot of scanned books that were scanned in color even though they are all text. Converting them to B&W speeds them up tremendously and allows Zotero to scroll pretty smoothly.

@jocabia and @hu-itanu I've found the same issue. The PDF viewer is anemic on many fronts. Good to know about converting to b&w, though for Islamic mss one then loses crucial headings in red ink.

@jacabia, setting Preferences > Advanced > Config Editor > "mousewheel.min_line_scroll_amount" to 50 helped :)

Thanks Alex. Just done the same (changing mousewheel.min_line_scroll_amount) within Zotero 7.0.11 - as following the update from last version the speed of scrolling was far too slow. Kept upping the value until happy with speed (for me, 100 suited). Hopefully I won't have to keep changing it, otherwise it'd be good if this adjustment could be within the actual PDF viewer itself rather than tucked away in Config Editor.
