[Question] UI test app for Themers?

So, I'm neck deep in my first theme (HoloGlass), and am FINALLY making heads and tails of things, but I had an idea that a quick forum & google search couldn't find: A simple test/dummy app that loads ~94.7% of the standard theme components of the main holo styles, to easily see changes and how the theme looks overall. Something like 4 or 5 pages (hierachy navigation) with the different theme styles, split/stacked action bars, a tab bar, and all the buttons and stuff, some of which open a few dialog / popup menus.

Does anyone know if this exists?

Thanks!
