I recently purchased Coda 2 after hearing lots of good reviews about Coda 1. After playing with it for a while, it serves quite well as a text editor, FTP tool, and front-end development program. If you have lots of sites to manage, the UI works quite well for switching between sites. The bracket matching feature could be better — I’d prefer a solid color for matching brackets rather than a quick animation over the braces.
One feature I do like with Coda is the plugin extensibility. Here are a few that I’ve found quite useful so far.
HTML, CSS, PHP Validator, minify JS feature, clean whitespacing:
