LOL changed my mind, after Reading what @Low Information Voter said. Want three steps, like a little wizard, so that they can follow what the client is "doing".

1) Pretty asciidoc preview
2) Kind structure selection dialog
3) Split view with disabled kind labels 

 I would just do the publish button, tho. No fourth dialog.

 We could have a little confirmation pop-up as one final exit hatch in case the user changes their mind.
