Years ago I the the Post-it notes software on my WIN machines. It would allow me to actually put a note right with a document without altering a document. Then when ever you opened the document there was the Post-it. I have a lot (100s) of long PDF files, many just scans and not searchable. I'm trying to keep having to flip back and forth with some list of what's important in a document. I'm looking for the easiest way to work. Thanks
