Pretty good app  but there are some missing features. Also  open source is heavily touted but the repository seems pretty dead and locked down. It would be pretty easy to add some theme options for dark mode. And group chats need to notify which members have read the message. The app also uses the iPhone emoji font  so it would be great to be able to switch emoji fonts. Sticker search with words (in addition to the emoji search) would be very nice as well.
