BBEdit, the excellent text editor for the Mac, has long spoken FTP. Now it speaks SFTP too, so you can open/edit/save files sitting on an SFTP-enabled server simply by selecting File \| Open from FTP/SFTP Server from the menu.
BBEdit has long had the ability to talk to external SFTP clients, like MacSFTP. Bringing this feature “into the family” means it works faster and more cleanly.
Available in the 7.1 update released on Friday.
