I totally agree, Liam! I remember working on a genetics paper and constantly having to Google terms like "epistasis" and "phenotype." Tooltips would have saved me so much time and frustration. It's all about user experience, right? If I were building a learning platform, I might even look at how something like Crazy Cattle 3D handles in-game tutorials; their approach is surprisingly intuitive. Accessibility matters!

Ever feel lost in tech speak? I definitely do! What's the quickest way to understand it all? For me, it's seeing terms used in real examples. When code snippets come with hover-over definitions, things click much faster than flipping through documentation.

Looks like that there are new options on the table but but both have been stalled for almost a year

This would be so useful!

It would be also great to store definitions in a single YAML/JSON glossary. The good example is at https://idratherbewriting.com/learnapidoc/docapis_glossary_section.html#reusing-glossary-definitions

there is https://gitlab.grnet.gr/terminology/docusaurus-terminology but seems work is stalled.

Even all related plugins on https://github.com/remarkjs/remark/blob/HEAD/doc/plugins.md#list-of-plugins are broken :(

As a workaround there're many existing React tooltips components (ie. https://github.com/atomiks/tippyjs-react). You can simply add it to your project (npm install / yarn add) and use it.
