So, I think this will be an elegant solution for managing shortcodes for me. =)
I am seeing an issue in the shortcode editor. The problem I'm seeing is that if I post large chunks of html, the edit screen expands to the full width of my screen, which messes up the layout a bit and then I no longer have the ability to click save. Meaning when I click save, nothing happens, as though some other element is sitting on top of it.
This does happen on Windows Chrome, FF and IE9. I also tested on 3.4.2 and 3.5.
