How to favourite a chat

To keep an important conversation handy, mark it as a favourite:

1. In your chat list, open the actions for a chat (long-press it or use its menu).
2. Tap Favorite. To undo, tap Unfavorite. You can also Pin or Mute a chat from the same menu.

Note: on the free plan you can have up to 5 favourite chats; Premium removes the limit. See Free vs Premium.
