Enhancements suggestions – WhatsApp Messenger Review

1) can we have a new UX to separate chats by subject/area. I’d like to be able to use different tabs to see chats with my friends in one place and work related on another so that I can separate them when I am working and when I am on a break for example. 2) provide the ability to sort chat messages manually or by different criteria’s others than automatically by most recent message received. Thanks
