Ah, I see. Unfortunately no, it doesn't save that information. I didn't want to get into saving passwords on the file system and have people yell at me for not encrypting the passwords sufficiently.
I'd be happy to save the FTP hosts and associated user id's if you opened a Feature Request
to remind me. If you really, really wanted passwords saved, I could make it an opt-in option and warn that saving passwords always implies some level of security risk, like Eclipse does.
