So Github have released their new Text Editor, called Atom. It's currently an invite only Beta right now, but it has got some attraction, even I myself have a copy of it. If you've ever used Sublime Text, it's very, very similar but is built on web technology (Chromium) rather than something more native, and already has a lot of packages, themes and tools ready for it. It's very user friendly but hackable at the same time, even allowing you to make your own Stylesheet for the editor.
It's currently invite only, but as an Editor it's off to a good start. It isn't as great as Sublime Text I will admit, but it's early days. I've found it very easy to use and I'd say it will make a great competitor to apps like Sublime Text and Adobe Brackets/Edge Code, and it has great Git integration (showing you what branch you're on as well the files you've changed, and how many changes per file).
