Will Monte - I've been playing around with exactly how to do this, I do agree with Andrew Boon that changing templates can cause undesired UX issues but I haven't found it to create any app-breaking issues, certainly nothing compared to the near daily torture that React and its parade of dependencies cause me and my sites.

I like the current Lucid setup on mobile that I have so much that I am gonna make it the default and leave access to the template switcher open on one of my sites.
