SFTP / SCP interface was added in 4.3.6b.
I think more features other than uploading and downloading will not be required,
because the user can operate files by command line.
However, if you have any idea about better user interface or better features, please post here.
Also, if you have faced problem about SFTP / SCP features, please post here.
Just started to use this today, its a nice feature thanks
