Brackets is kinda awesome

Check out Brackets, an alpha-ish open source code editor for the web from Adobe.

 
Basically it looks like it’s all Chrome (the code itself is JavaScript/CSS/HTML) inside a light shell to handle things like local file browsing/writing. As such it’s extremely fast and a Linux port shouldn’t be too hard. It has some really interesting and novel ideas, like the inline CSS editing while viewing HTML. I am very happy with Sublime Edit, but my dev kit promiscuity is legendary - I’ll be keeping my eye on this one.
