Flow

Shareware; $29

Current Version: 1.2.7 (March 22, 2010)

Flow is a new FTP client built exclusively for Mac OS X Leopard. Flow streamlines both transferring and editing files by leveraging your high-speed connection. Key features include:

• QuickLook - Just like the Finder, Flow can QuickLook pretty much any file - images, movies, music, PDFs, text documents and even web-pages.
• Dropmarks - Drag a bookmark to your desktop to create an Instant Droplet. Drop a file on its icon and watch as your file is quickly uploaded in Finder-like copy-window.
• Solid Connections - Support for FTP, SFTP, WebDAV, .Mac, and Local Connections, concurrently to allow multiple transfers and editing sessions to take place at the same time.
• Editing - Edit in the sleek internal editor (with tabs, syntax coloring, live previewing, and code sense), or with another editor of your choice.
• URL Copying - URLs to your remote files can be copied instantly, even automatically after uploading. We promise that once you use this, you'll never be able to live without it again.

Version 1.2.7 adds/changes the following:

• [Fixed] Most common crasher, relating to key-downs in the column view.
• Issue where progress bars might be blurry under Snow Leopard.

Flow is distributed as a 15-day fully featured trial, and is available for purchase for $29.
