This is a plugin that helps you navigate through a PDF document in Logseq when there are internal links. Jumping back to where you click the link is painful; this plugin adds button to the PDF toolbar, which provides go back and forward functionality.
Please close the previous document before opening another one to clear the history. (will resolve this issue later)
If the buttons do not appear, please close and re-open it, for the first time of loading a PDF may be slow.
