When you are in the column for a group (corps, band, etc) and click on the schedule link in that column, it would be helpful to either show just the groups schedule, or just all of the group types schedule (only corps, band, etc)

That's similar to the idea I had here

Except your's just chooses the category by clicking on your group. Which is another legitimate way to do it.
