Names of collections in menu

[arjendeetman]

Hi,

Thank you for making this nice theme available. I am interested in using it. I only have one question. Can the names of the collections be visible in the left menu, like in the original Gitbook project? Please see the example below with tokens and components as collection names.

Best,

Arjen

I could add something myself; see https://arjendeetman.github.io/jekyll-gitbook/

See the commits in this fork https://github.com/arjendeetman/jekyll-gitbook

Can you add this and make it optional? Turn on or off via the config file?
