Hi there! I would love it if Adobe would add the ability to save a collection of open PDF tabs from a previous session to reopen later. It would be great if I could save a collection by date, project name, client name or whatever. You already have the "Reopen PDFs from last session" feature but this is limited to the PDFs in my "last session". It would be great if I could do more. Yesterday I was working on a case which required me to view several PDFs. I planned to use the 'reopen' feature the next morning to continue where I left off but because I had downloaded and viewed an email attachment just before signing off, it reopened that document instead.
