Brackets is cool. definitely great to have it as an option. Most important for me for new additions is the multi-line / cursor editing. I use Notepad++ for that but brackets could replace notepad++ if it had it for me.

That and the other day I had this xml file I needed to look at and brackets didn't open it on Mac. Right-click open with, Brackets. It failed. Not sure why it wasn't a bad or large file at all. Text-wrangler opened it fine.
