Add a reload/refresh button when viewing a file

Often I view a file directly within SmartFTP.
It would be nice to have a button on the viewer toolbar to reload the latest version of the file from the server.
Currently, I click to view the file again - and I end up with two tabs viewing the file - the first tab then asks me if I want to reload it. It would be better if I could reload it from the source ftp site upon demand (or automatically if it gets changed on the server).
