Filezilla Best FTP Client

After paying for and using WS_FTP for years until they ruined it with a disastrous new GUI, I turned to FileZilla which was very good but lacked the old WS_FTP's wonderful feature "Remember current local and remote" directories, very useful when working on large multi-directory websites. But not now the latest version of FileZilla incorporates "Bookmarks" which allow you to save and subsequently return what ever directories you specify; eg you can name a bookmark images or css and then go directly to the relevant directories.

ALSO you can specify "Use synchronized browsing" which means that changing a directory in window causes to change simultaneously in the other!!!
