Atom Text Editor
Atom Text Editor project started few months ago and it seems to be hot these days. Up until now it was available only for Macintosh but since two days ago it became availble also for Windows 7/8. It has quite a lot of nice features but it still in beta version. You can contribute to the project if you want via github were you can fork the code. Download it from here.
At GitHub, we’re building the text editor we’ve always wanted. A tool you can customize to do anything, but also use productively on the first day without ever touching a config file. Atom is modern, approachable, and hackable to the core. We can’t wait to see what you build with it.
