FileZilla is great, but the default configuration is to save all configuration files & sites to local folders.

Here's an elegant solution to change the default directory. Just copy fzdefaults.xml.example from [FileZilla's install dir]/docs and place it in:

• Linux/BSD: ~/.filezilla
• Mac OSX: Contents/SharedSupport/
• Windows: put in same directory as filezilla.exe

Alternatively you can also point to a shared folder on Dropbox, and share your config and sites across multiple computers. Just make sure you have a strong password on Dropbox, for obvious reasons.
