When I work in Dreamweaver, I can work in code/design or split view, and the document window is surrounded by palletes that contextually provide ways for me to modify what I’m working on.

Although Coda allows you to split the window horizontally, there seems to be other way to have your CSS palette available while you work on your design, but the CSS editor seems meant to be displayed in the whole window, so allowing vertical splits (my preference) would also require at least the CSS editor to be redone a bit, it seems.

However, other things are an improvement to DW – I think the ability to switch between text and GUI css editing is nice in the CSS editor, for example.

There are some things that GUI apps are just nicer for. I can get precise alignment on a page layout by handcoding the postscript myself, but InDesign is much quicker.

However, I will say that while I appreciate the effort, I find a lot of the interface to be non-standard and confusing (perhaps users of other panic products wouldn’t have this problem).

For the price (US$79) though, it’s pretty nice, although I don’t know that it’s the Dreamweaver killer some others have said it is.
