Bookends 13.5.2

Sonny Software has published Bookends 13.5.2, updating the reference management tool with modernized and streamlined code. The release also expands PDF thumbnail icons, lets you use default attachment folder subfolders to any depth when attaching files, ignores partially downloaded PDF files (ending in “.pdf.part”) when watching the Downloads folder, displays superscripts and subscripts in Subject Bibliographies when sent to the Bibliography Window, fixes a bug where moving to another reference using the Links Inspector could discard edits, and resolves an issue that prevented Bookends Quick Look from working.
