Here's an idea for an additional layer of permissions.
Under the permissions for Banking, it would be nice to have a yes/no option for allowing the user to see account balances.
The use case here is that we have bookkeeping users that need access to banking to process different transaction types (sales refunds, transfers, etc.), but we'd prefer they not be able to see the balance.
This is a "nice to have", but I do think it would have value to others.
