Hi all. I'm working on updating several of my plugins, and I'd like to add drag and drop visual editing to make them more user friendly. I've seen very few free plugins that have this feature and all the google-fu I can muster hasn't turned up any tutorials.
I'd like to allow a user to pick from several layouts for a custom post and then be able to edit in that layout. If they wanted to use the tinyMCE editor, they'd be able to switch back to that.
Are there any good tutorials and/or frameworks for adding visual/drag and drop editing to a custom post?
