This tutorial walks through how I was able to make the top branding bar in ELMS "follow you" as you go through the site. The modules used in this video primarily are Appbar, Context, Menu Block, Menu Icons, and Menu Token. There is also some custom code in the elms_spaces module which extends Menu Token's default functionality but this should help you build out your own consistent region in your projects. As always, feedback is much appreciated!
Editorial note: I call a project "Menu Translate" in the first part, what I mean to say is Menu Token.
