Today WhatsApp released a new feature: custom lists. These are the evolution of chat filtersintroduced earlier this year as a way to find messages faster.
Custom lists allow you to filter your chats into custom categories of your choice. You can make a list for anything: family, work, your neighborhood, and so on.
Creating a new list is as easy as tapping the + in the filter bar at the top of the Chats tab in WhatsApp. To edit a list, long press on it.
In the same way as your favorites, you can add both groups and one-on-one chats to each list. Any lists you create will appear in the filter bar.
The rollout of this feature has already started, but it will take a few weeks before it is available to every WhatsApp user.
