[ask HN]: OS X App for multiple File Transfers/Remote Sessions?

I would like an app that lets me have multiple sessions (FTP, SFTP, SSH, SCP) open at the same time to multiple remote locations. Something where in the window for each connection I see local and remote contents and I can easily move things back and forth via whatever protocol I need. Yes, I can do this via a terminal or Fetch or FileZilla technically but they all dont work perfect. Or maybe instead of a window for each connection a single window with a 'tab' for each connection I have open. I usually have a lot of sessions open and switching between the terminal and Fetch is just a nightmare.
