# Description

Currently, whenever there is a rendering problem with a math tag big red color is displayed.
I propose to change that and display the input LaTeX code instead with the error message in a footnote or a popup.
Moreover, a tracking category should be assigned to that particular page.

1. How to assign tracking categories?
2. How to bring the message into the footnote, i.e. are there build in MediaWiki functions I could use, or do I need to use plain HTML?

You assign tracking categories with

\$this->mParser->addTrackingCategory( 'math-tracking-category-error-foo' );

Where math-tracking-category-error-foo is a registered i18n string; Cite only has one, I think, but you can have multiple if it's needed.
