Suggestions to add invite friends, sign for read messages and typing...features on social chat

Components

Social chat is a great messenger application on open source platform that allows users to chat and communicate with friends via email.

Proposal

Adding of invite a friend feature to social chat would be of a great important and benefit for users and the app. This feature would allows users to invites friends from other social platforms to join them on social chat which might be another way of promoting the app likewise. This would help because users will not only bounds to friends the app offered them but can also invite their own preferred persons to the app thereby makes chats more interesting with familiar people around.

I suggest show sign for read messages and "typing" features should be added to social chat as it would allows users to know that their messages has been read by the intended person.
Typing as a feature would help users greatly as it will performed action made by chat partner and would also gives users the sense that the party is actively on chat.

Mockups / Examples

I suggest invite friends feature should be place here as a options on the social chat.

Here is the feature from another messenger.

Afterwards users click on the feature, here shows up multi media platforms to invite friends

This where I think this feature should locate as it is locating on other messengers like WhatsApp specifically.

Typing feature from other messenger located below the chatter username..
And the green sign which indicate that the message was sent successfully to the recipient.

Benefits

The availability of these features would give the sender the certainty that the message he/she sent has been read by the recipient, as it will show the sign that a message has been read by a recipient.
Thus, is also beneficial as users will be sure that the message was received and as a result, it will be difficult for a recipient to deny the fact that message isn't read because of the notification sign seen by the sender.

Showing the feature "typing"………will allow users to know that there is a kind of reply action going on. It makes conversation interesting knowing that the person you are chatting with is about to reply to your message, this gives rise to a long conversation between the parties because the feature make the chat more real and not chatting blindly.

Invite a friend feature would be a great benefit for users of this app as the feature would allows them to invite their loved friends from other media platforms to join them on social chat and the result, users will be more comfortable to chat with known persons after which they joined by invitation of which would be extremely pleasing and user friendly.

However, having these aforementioned features would make social chat app more unique and users will be more glad to use the application more and this will improve its popularity.
