I think it would be nice if there was an option the copy a previous copy back to the clipboard for pasting again in other applications. This would be a useful feature because I usually find myself with a previous selection that I would like to paste into an app.
Just clicking on an entry should do exactly that, and it works here. If this does not work, please specify if this is specific to Wayland (neon unstable).
Either trivially resolved as per comment #1, or is pending more information.
