I read a lot science papers as PDFs in Edge. They are full of hyperlinks referring either to other parts of the paper, or to external resources. It is now possible to open an external link in a new tab (which was not possible in the old Edge), so that's great.
However, beyond that, there is no ability go back from a followed internal hyperlink. E.g. I click on a link to a reference in the middle of a long paper, I get taken to the bibliography at the end of the same document, I now want to go back to where I was and I have to scroll back to find my place. Old Edge also didn't have this feature.
Adobe's PDF Reader has separate back/forward buttons in addition to next/previous page buttons which allow one to follow the internal hyperlink history within the document. Something like this would be a great addition to the PDF reader. Maybe it would be enough to overload the browsers back/forward buttons here?
