I really enjoy using Syncthing on Win and QNAP.
I think it would be great to have the option to change the behavior of the list of recently changed files, that you can access by hitting the tray icon. At the moment the list only contains new files been added from a external node to the local node. I think it would be helpfuld to add as well the files the local node adds to the folder. On a timestamp basis. This is how dropbox does it as well.
