Viewed Message visual indication.
When one sent message , sender should know that receiver has viewed or not ? like whatsapp indication to viewed message or recieved message indication with double tick and blue tick to indicate viewed.

This is critical functionality, and Google Hangouts, iMessage, WhatsApp, FB Messenger, and other chat programs have it. It may prevent our entire department from switching to this tool.
