When editing the marked up mediawiki text, it would be more convenient if it has a syntax highlighting (instead of plain black text). I also contribute to Arch Linux wiki, and it has such feature. Can we add the same? In their [version page](https://wiki.archlinux.org/title/Special:Version) it can be seen that they have installed [CodeMirror](https://www.mediawiki.org/wiki/Extension:CodeMirror) extension. It helps a lot when editing tables for example. Also it highlights interwiki links, templates, headers, formatting, etc.
