As things are now, the only way to sort the event collection grid is manually. The most intuitive sort order is to list classes in the same order as currently shown on the calendar, namely, by date and time. But if you set it up that way, by the end of the week the first few listings are in the wrong place, since we offer a mix of classes that recur every few weeks. Ideally we would have the option of choosing an auto-sort setting such that the sort order is determined by the app, taking into account the current date and time and all the active schedules.
