Hi Daniel. And thanks for sharing another great plugin with the Moodle community. I personally love simple plugins with clever idea - just like this one! Especially if they are implemented in a clean way and the code is easy to follow. In your tracker, I left just a tiny suggestion for explicit declaration of dependency on mod_glossary even if it is a standard module.

I am happy to approve this now. You are cleared to land, welcome to the Plugins directory!
