While I do agree that DreamWeaver is useless, I don't agree with your specific points.
Integration: They recently added an
Extract
-mode, which generates fairly clean HTML and CSS from a .psd and embeds images in proper resolutions.
GREP: On CTRL+F, you can use regular expressions.
Muse: Muse and Dreamveawer have overlap in functionality, but they're seperate products.
Auto-completion: I don't see why it would hurt. You still write the entire code yourself, including thinking about what to write - you just type less and thus avid typos. But that's nitpicking: Good answer. —
