Moodle Multi-Language Plugin
I created a transient* Moodle plugin using JS, jQuery and CSS for the University of Wales, Trinity Saint David that allows users** to insert content blocks that automatically show/hide themselves based on the Moodle instance's current selected Language.
The tool (or Moodle MLTool, as I've taken to calling it) is compatible with Moodle instances that use either TinyMCE or Atto editor types.
Greatest focus was on cleanliness and usability, with a minimum of steps to produce the desired result.
Get in touch for a copy of what I have so far!
* Semi-Modular, and not baked in to the core Moodle files so it's easier to move and upgrade
** primarily editors, but the ability to allow use for students is present
