This is really cool! I can see it becoming super useful, and bridging the missing overall site upcoming events list in the core functionality.
For some reason, the toggle to hide non-event containing topics isn’t working for me. This is with the Horizon theme (haven’t tested it further sorry). I wonder if what is needed is for the filter to handle Event filtering rather than hiding them via the TC. I’ll put in a feature request for that:
Also, we really need the New Topic button to become a New Event button instead on the Event filtered list. Is it possible to add that to the TC?
