It would be very valuable to our groups/users if there was an "event" filter on the general calendar. This way people can filter out the volunteer needs and just see upcoming events. Our organizations have requested this also as a way to see what other events are scheduled around the time they are planning an event to make sure they aren't holding a conflicting event that may create more competition for volunteers.
Thank you for posting this suggestion on the Forum and explaining how this would be an improvement for your site! I've added this suggestion to our internal Enhancements board where it will be reviewed by our Development team.
Have a great rest of your day!
