Church admin is a great plugin for setting up church website and for church administration.
Agree that is an important feature for church administration.
Here are some suggestions for this feature request:
Giving/donation can be tracked and export by household.
Giving/donation can be gave by anonymous.
Giving/Donation can be categorised as different purpose and custom field
One more feature can be consider together is the financial status of the church.
Financial status can better helps to run different strategies on the church, better coordinate the resource on different ministries.
please consider these feature.
Thanks
