Something that would really be helpful for us is the ability to add internal-only content on an externally-facing solution/kb article.
It would function similar to a "teacher's guide" version of a textbook, as an example. It could provide additional behind-the-scenes information about the "why" that's the solution/workaround we're giving or some other additional, confidential information about it.
The simplest way I can think of to implement that is some additional markup like
[agent]
This can only be viewed by a logged-in agent!
[/agent]
that can be used in the WYSIWYG editor.
