SUManager Plus

The troop role history form (see Troop Details) keeps track of the people who had past roles in the troop.  You can enter history directly or you can use the Move to Role History button on the Current Roles form.  The form grows to accommodate as much history as you care to keep.

As is the case with nearly all lists and forms in SUManager, you can filter the list by the type of person (adult, scout, other) and jump to the selected person's detail record via the Go to Person button.
