WhatsApp has rolled out a new feature called 'Starred' messages that will now let you star a message for reference later on, similar to bookmarks in emails.
The feature was been introduced in iOS9 first and is not yet available in the Google Play Store for Android phones.
With the update, WhatsApp users can tap or press hold their messages for the app toolbar, which now includes a star sign, to add it to the 'Starred message' folder.
For iPhone users the 'Starred messages' folder appears in the contacts section, while for Android users it's in the 'Options' dropdown from the Main Menu.
