Extendamac has released the first version of Flow, an original FTP program. The software is designed to streamline certain tools that normally fall outside of FTP clients; predominant is the inclusion of a code editor, which is used to write the likes of HTML, and includes features such as tabs, colored syntax and live previews. Along these lines Flow also boasts integrated QuickLook support, letting users preview the content of various files before formally downloading them.

Other features of the client include the quick creation of file URLs, and "dropmarks," which are desktop shortcuts that automatically send files to a particular server when icons are dropped on them. Flow costs $30, and requires Mac OS X Leopard; supported protocols include FTP, SFTP, WebDAV and .Mac.
