Is a free editor influenced by Sublime Text for OS X 10.8 or later, Windows 7 & 8, RedHat Linux, and Ubuntu Linux (you can probably build it for a different OS)
Sure, it does not have a one-click compile, launch in emulator and repack to 3dsx feature but since the editor is modular anyone can write a module specifically for ninjhax-compatible binary development.
That seems massively cool, but I get the impression that people want something that will just work
