Using tags to filter displayed markers

By introducing user-defined tags, I could group collections of markers to finer details. Here, we're looking at the POPOS I've visited, but only those on California Street, since I was careful in my authoring to think about tagging my POPOS markers to street level, along with city, state, country, and other tags.

What I realized is that the system I built supports tags, but it was me as a user who came up with the notion of hierarchical views on my POPOS visits. I wanted a system with simple rules that enabled complex outcomes, and this was beginning to have that flavor. Obviously, I could do more than POPOS.
