I used to use Preview for this purpose, but I realized it has since changed... I really liked how the "notes" in an older version of Preview (not sure which) were off to the side in the gray area, so as to not obstruct the document itself yet still be visible in its entirety. Currently, I find that notes "minimize" and only show when I click on them. And even if I were to have them always visible, they'll always be on the document and not off to the side away from the material. Does anyone here know an alternative annotation app that has what I'm looking for? (Similar to the older version of preview with notes off to the side and always visible.) If not, is there any fix in Preview for this? :/ Thanks!
