Even so, as much as I like Panic, I don't know if I'd quite support that claim. Dreamweaver did a lot of those things sans the terminal, even if it did a lot of them less elegantly. (And I'm sure someone will explain how Emacs could technically have done all this since 1953 or whatever. I kid, I kid!)
Having said that, I'm still interested in seeing what they manage to come up with. I admire their products even when I don't regularly use them. (This includes Coda.)
