Feature Request: Downloading files from the server to the client

[Void-025]

An option in the right click menu to copy the files from the server to the client machine would be very useful, maybe next to "Open" and "Show in file manager" (By the way, can those be used via sftp or similar, or only things that are mounted? This would also be a nice feature to have).

Alternatively, a way to add custom commands to the right click menu like transmission-remote-gtk has to allow users to write their own download scripts could work as well.
