There's an option to put NZB's loaded from watched folder to be put at the top of the list, but nothing to put a NZB clicked on from File Explorer at the top of the list.
This would be handy since I don't clear my download list during each session, so if I double-click on a NZB to open Newsbin, I'd like it at the top of the list because it's a priority. Right now I have to wait until Newsbin loads and refreshes the list before scrolling to the bottom to move the files to the top.
