My latest plugin is a simple piece of code that replicates the `code in backticks` function used in the wp.org support forums
. It works in posts and comments, although it’s mainly intended for the comments section (because there are already many, many, many plugins for pasting code into posts).
(If you use it in posts, you must use the code view–it will not work in the visual editor, I assure you. By that, I mean that you need to have the visual editor disabled in your profile. Otherwise, when you go back later to edit the post, it will try to open in the visual editor first, and it will get screwy.)
So now when folks are asking me questions about my plugins, they can just insert an error message or a piece of code right into their comment with no difficulty at all. How lovely.
