Coda 2 actually seems to take a step backwards and it certainly doesn't measure up to the rep that Coda 1 earned out of the gate. It makes some jumps in terms of ancillary UI widgets but it doesn't dramatically change or improve workflows over Coda 1, as far as I can see in 15 minutes of exploring. It doesn't integrate well with dynamic sites or version control from what I can see.
At a minimum, it'd be nice to be able to have a first-class embeded webkit browser as one of the options for the frame/panes but the closest they come is a preview – which works really hard to only render the file you're working on (but does include a small URL field).
The big new feature is MySQL integration? Clearly they had a very specific user persona in mind – and I don't really know who that is... but I think they're from ~5-10 years ago.
I think I'll pass, honestly... sadly. I hope I'm just missing something because this was an update I wanted to see.
It's not as if Transmit really brings that much to the FTP world, but people seem to really love it.
I've also found that FTP clients on Mac are missing a nice feature found on many Windows clients: multi-part (accelerated) transfers.
I've paid for Sublime Text and it does the job (and is my preferred editor on Linux), but, for me at least, it doesn't "fit" on a Mac as well as Coda. And I can't really tell you why that is.
As you become a more proficient developer, you begin to appreciate the configurability and extensibility of textmate/sublime/emacs/whatever over the polished but limited workflow conventions of Coda. (At least I did, Sublime FTW!)
I think this is very true, and it applies to their entire product line. It still boggles my mind how popular Transmit is.
Having said that, extensibility isn't for everyone. I have licenses for Coda, Textmate and Sublime, and I like them all.
Personally, I do like the one-window approach that Coda takes, but that's a ultimately a taste thing.
I think it's on par with Textmate and currently $34
