@sanscontext I spoke to Vero about this and from UX perspective it's far better to introduce the right navigation as it is on other subpages than replacing current left navigation.

This is what we are proposing:

1. Adding a "Glossary" item to the left main menu (frame number 1)
2. Headings from content (frames number 2) will be menu items on the left menu (frame number 3)
3. The left menu stays as it is, we are not replacing it

What do you think?

Hey @jedrzejchalubek I disagree here, and we want this to replace the left-nav and be one of the "microsites" mentioned in #172 so we can present the terms as a single consolidated set of information separate from the rest of the docs.

The other reason for this is that there are going to be a LOT of glossary terms, which will make the right-nav difficult to use. If you were to build the right-nav with more than 50 items, you'll see what I mean. We want to allow people to scroll through the left-nav to find a specific term they're interested in.

Since this page is already built from a YML file it shouldn't be difficult to just loop over it to create the left-nav.
