A better way to insert preformatted snippets into content/wysiwyg?
The perfect solution hasn't presented itself, but I settled on using specialized content types inside a parent content type, (via Entity &amp; Entity Reference fields) and then using Better Formats, Wysiwyg with CKE, Fieldgroup, Conditional Fields to make a user interface that presents all the myriad options in a nice clean manner.

I'm kinda proud of the result, I expect I'll eventually reuse the system somewhere more public so I can show it off.
