Work with a Subset of Records with List Views
Sofia, a Development Associate at No More Homelessness (NMH), is busy—we learned that from her calendar in the last unit. She’s always looking for tricks to help her get her daily tasks done more efficiently, and one of the first places she turns when she wants to get certain information quickly is list views.
