Topic: Coda: Sweetest Programming Environment ever??
I downloaded the demo and was thoroughly impressed with how well they integrated all the aspects of development...you get FTP, shell, html, css, webkit previews, autocomplete and even documenation all in one app. There are only 2 downfalls
1. Only available for Mac (sorry PC lovers!)
2. Very PHP-centric
While #1 is probably a no-go, i think if enough of us bug them to support Rails, they just might do it!
Download the demo and if you like it as much as I do, give the folks at Panic a ring: email@example.com
