I am very excited about the beta pdf viewer which allows for annotations an notes within the pdf.
Often, when I read a paper, I want to look back at the metadata (e.g. to see when and where it was published), and now I have to go back to the library and find the paper.
It would be great if the library metadata could be integrated into the viewer, and made editable too.
This is especially relevant for notes metadata field. The highlighted notes that you make in the pdf viewer are not searchable. It would be great if the beta viewer would provide access to the 'note' metafield in the library so that I can make searchable notes whilst reading the document.
