Is there a way to add and view bookmarks in pdf-tools? Or else How could I go about adding this feature?
I'm not actually sure if this is even a feature of pdfs. All I know is I can do this with document viewer app on ubuntu.
org-pdftools is able to set pdf page links, which can then be saved in an org-mode file. Alternatively, if you want to have something embedded in the pdf file, you can add an annotation somewhere on the page (see annotations keybindings list), and then list/jump to them via
C-c C-a l and
SPACE. I think that these two features are the closest thing that there is to the bookmarks feature in document viewer.
