Button on list view to assign value to field
Such as hit button to populate current date into field.
That way, you don't have to edit a record, hit the date then set. Saves a few keystrokes.
Similar to the option for entry method for Boolean entries - you can opt to check/uncheck them on the list and/or entry view.

Also include the to affect a field on all entries if certain conditions are met. For example, cashout an inventory based on a batch number etc.
