Currently in whatsapp you can reply to user during chatting by just holding the chat and start typing in text editor, it automatically attach the chat for reply, also you can hold the chat and press the (i) button in the top to reply the chat user.
Now with the update of Swipe to reply feature it allows to reply a message using gesture, these same feature is implemented years ago in Whatsapp for iOS. if you swipe a message to want to reply, using gesture option whatsapp automatically loads the reply message in context to save extra time, see the below video reference..
Expandable group participants list
In whatsapp groups if there is more than 10 participants, whatsapp shows a “More” option in group info area, when the user clicks the More option the rest of group participants are shown, this saves the page size in the group info.
Whatsapp Dark Mode UI
There is talk going around for Whatsapp Dark mode UI as like in twitter for users to use in night time, this is an good option for users who chats more in night time and also technically in dark mode UI the color pixels are won’t work, these saves the battery power.
