Cool plugin, but I couldn’t make it work for my purposes.
- The plugin seems designed for ad hoc queries on tags–I couldn’t find a way to save queries, unless pinning does that.
- The pseudo folders only exist in the plugin’s tree structure, and they aren’t recognized as publishable folders by the Webpage HTML plugin.
The plugin does look really useful if you organize your notes rather than folders or if you wanted to organize notes, say, both by date and topic. If I were to use it regularly, I’d need to learn how to structure my tags and the plugin so that I didn’t see every possible permutation branch—there is so much information that my brain hurt trying to make sense of it. 
My tags are currently applied too randomly to work well other than with a single tag search.
