Just curious which app you use to SFTP your server. Does OS X support SFTP natively? I couldn't get it to work. Anyway, I currently use Cyberduck, but is there a better program?
for free i don't think there is a better sftp option. some people would say fugu or the osx filezilla, but i think the 'duck is much better. (fugu seems to have ceased development, and filezilla isn't very "mac like".) paid sftp software is a different matter, you have many excellent options, transmit, forklift, flow, yummyftp. i like panic/transmit's reputation, they make pretty decent mac software, flow was buggy/crashy (for me) and forklift and yummyftp seem good (yummyftp is a little more complicated, and forlkift is a revision or two away from matching transmit imho.)
I use Cyberduck of Fugu. You can also SSH into the account through Terminal if you want something OSX native, though no GUI. I use it to rsync with my account and make some backups.
I use Fetch and BBedit for my SFTP needs. Push all the files onto the server with Fetch and then I can edit them directly off the server with BBEdit.
