Love the plugin! To better suit our client's needs, I am hacking into the PHP files and replacing the strings for "Categories:" and "Tags:" to change them to more user-friendly "Audience:" and "Location:"
This will probably have to be re-done every time i update the plugin. It would be handy to have a setting on the admin menu to set the display label for Categories and Tags, so that no matter what a users is using as their taxonomy, the display can be tailored to better suit the audience's expectation. (most people looking for an event don't know or care what a category or tag are, and would more likely want to filter results by location, etc).
