Preview Internal Links of PDFs
When reading a research paper, in-text references often link to the "References" section at the end of the paper, where the full reference is listed. It would be helpful to preview the linked part of the PDF to see the referenced paper without losing my current spot in the document. The attachment shows how this is implemented in the PDF reader of my computer.
This would really help me as well. I often read scientific books in goodnotes because its easier then to switch to other documents I currently work in. However, always having to get back to the page after loking at a referenced equation or image is annoying.
A valuable alternative to the preview would be a button to jump back to the position of the last link that was clicked. This would also do the job, I think.
