How to create an "Airtable Universe" style sidebar with shortcuts to views?

[Y_K]

The https://www.airtable.com/universe interface is awesome, its left sidebar allows you to view different parts of your base without switching between tables and views.

How to make a sidebar like this one for my own base? Essentially it is a two-part iframe HTML page but I just wonder if someone has done a more complete and secure template that could be implemented without advanced HTML knowledge.
