Mark papers as read (or being able to do so)

Having uploaded lots of papers, I sometimes have some difficulties figuring out which ones I've read already and which I haven't, or it can take some time for me to find/establish which papers I haven't read yet.
So my suggestion would be to include a line (below title and author(s)) in the overview of uploaded papers with "completed/read" or a percentage when you haven't finished listening to it from start to finish.
