I definitely outgrew Coda a few years ago although I occasionally fire it up to use its visual grep. However, in the time since I switched to other editors (Chocolat, Sublime, and now Atom), my workflow has changed significantly.
I'm ready to do a clean install for Yosemite, and maybe it's also time to give Coda another look. I had been planning to switch back to Sublime after giving Atom a shot (there's a lot to like, but it's slow as molasses and the autocomplete is total garbage). So much of my workflow lives outside of my editor these days, so maybe it makes sense.
