Hi,
currently it is not possible to use a "site" with multiple credentials.
For example: I am connection via SFTP to a server. Sometimes I am using the username "foo" and sometimes I am using the username "bar".
Currently I have to create two sites in FXP to support that (or change username each time).
Why don't you allow an empty username field, which will result in prompting the user when the server is requesting one?
This would allow me to create a site and set up my SSH key (because "foo" and "bar" will accept the same key). I could use this site for "foo" and "bar"...
I hope you understand me
This is currently supported by WinSCP and Putty.
