This request incorporates a few ideas. Currently, one can only view one note at a time, and that note covers nearby text while you are looking at it. I would prefer notes (i) written in the margin, so as to not cover the text; (ii) that remain open until explicitly closed. A bonus would be control over font size, so that one could write as much text as desired in the available space.
Hi we now have sticky (post-it) notes you can move anywhere on the PDF!
agree... this would be a great add on...been asking various pdf programs for this for a while
