The VNC Viewer URL Editor is an application meant as an add-on to an existing installation of the Real VNC Viewer 4, which can be downloaded
Here. Once the URL Editor is installed, you can use it to remove existing URL from your VNC Viewer History, so that it no longer shows up on the list of visited remote servers. You may want to remove the URL from the VNC Viewer history either for privacy reasons (if you are at work), or for security reasons (if at home).
