Looking around for hours, I could not see anything even close to what I saw here: http://www.youtube.com/watch?v=Y2Bu5NoYZ7M&feature=player_embedded
As you can see, they created their own editor for Wordpress (and not just some changes for TinyMCE), its entire editor, even with the ability to switch to TinyMCE.
Does anyone know how to create custom editors for wordpress without changing the main files and only using a custom theme? I'm starting to think it's a regular meta box ... but I'm not sure.
Any hint would be much appreciated!
