Save user preferences for filtering Activities tab listings
The requirement is to persist the last used values for the two activity type filters on the contact Activities tab => "Filter by Activity Type" form (activity_type_filter_id and activity_type_exclude_filter_id) for the logged in user.
The filter values would need to be saved onChange since there is no search form POST, and loaded from the DB when that tab is accessed.
It's causing a lot of problems for users
