Add the currently open paper to a collection
Sometimes when I'm reading a paper, I want to add it to a Collection. It seems that at present, there is no way to do this from the PDF/Paper Viewer tab. I need to go back to the main overview, find the paper, and then drag it to the collection. Am I missing something?
We could consider adding a way to do this from the PDF reader, but I wouldn't really expect it to be very common. (I believe you're the first to request this.)
