Hi, I would be glad if you could add a fuction, which will allow us to summarise and write notes right next to the page. I often upload pdf textbooks or research papers, but there is not enough space next to the text. For example Cambridge Spiral allows you to add a note next to the page you read, so it does not cover the text on the page. I would love that fuction if I could write the notes by hand. I think it will be useful mainly for other students who use Goodnotes to write and highlight in textbooks as well.
