1 - I am on the page 10 of an PDF, and I start taking notes.
2 - I take notes up to page 7 (7 pages of notes for the page 10 of the PDF)
3 - I move to the page, let’s say, 12 of the PDF (or any other age it doesn’t really matter)
4 - Now I go back to the page 10 of the PDF, I will be on of page 1 of the notes, I will have to change back to page 7 on the notes.
In step 4 I would like to find the notes in the page were I left off, and not on the page 1, every time, that really bothers me, I change pages all time while I am taking side notes.
