Show list of methods in the navigation pane?

[SystemParadox]

We are currently looking at switching to esdoc and it looks great. My one question is - how do we get it to display a list of methods in the navigation menu on the left when looking at a particular class? It's hard to get an overview and navigate within a large class.

I've looked through the source for esdoc-publish-html-plugin but I couldn't find any options. Is this something that could be implemented?

Thanks.
