i revisited this today, fixing some minor bugs in the code, making it more efficient under the hood, adding some minor functionality (an optional map thumbnail, a taxon input box), and changing the formatting a bit. i also put this up in Github so that you don’t have to run your own local version of the code (unless you want to).
