Components
This application allows you to send and receive messages in real-time using Firebase services. It is an open source app, which enables users to chat when logged in.
Proposal
My suggestion to this open source app is that
-They should include video chat to enable the users see who they are chatting with and also help for the fast interaction or communication of signed in users.
-I also suggest that they include "create group", it will help the users to be in a group chat i.e from 2 and above members in a specific group in other to chat, share ideas and so on.
Mockups / Examples
This is how it should look like when the "create group" is added to it.

When the video chat is added, it would look like this

Benefits
-If the video chat is added to this open source app, signed in users will be enable to communicate faster and they will be able to see who they are communicating with.
-And also for the "create group", if it is included in this app, users will be able to chat in group and also pass important informations among themselves. If this features are added to this app, i guess the app would look more amazing.
