For plugin development in Kibana, it is nice to use eui so that it has the same styling as the rest of Kibana. And it is really nice to be able to go to https://elastic.github.io/eui/ to see the latest eui settings.

But if I am targeting different versions of Kibana (such as 6.2.3, 6.x, or 7.x), I need to see different eui documentation for each version (Kibana 6.2.3 => Eui 0.0.14, Kibana 6.x and 7.x => 0.0.33).

Now, I can clone eui and run the documentation manually myself but it would be really nice if the eui documentation site (https://elastic.github.io/eui/) had a switcher between different versions. You wouldn't need to have every version be available but at least the versions used by supported versions of Kibana.
