I spent a couple of days updating and fixing the dialog, it was probably a waste of time, but I learned a few more things..

I think it should be removed. I don't think it's of much use since HTTP (proxy) support was removed (it should probably be reimplemented using a third party lib). But there is FTP proxy support.

I guess this makes sense if you're using gftp without direct internet access or something, but need sources that include FTP servers in a Local Area Network (local hosts) and servers reachable only through proxies.

Is this of any use to anyone?
