Messages States
Each sent message has a state icon to its right that indicates whether it has been sent or already read.
Possible states are:
Sending: the message has not been sent yet.
Sent: The message has been sent and was received by the recipient.
Read: the message has been read by the recipient.
In the case of group chats, state will only appear once everyone in the group has read the message. Hovering over the state of the message allows to get information about who has already read the message.
Menu
Access by pressing the icon 
located in the top bar of the chat window.
Remove history
Deletes all messages in the conversation for the user. For a group chat, once its history is deleted, it cannot be accessed until a new message is received.
Add user
For a private chat, this option allows to add users to the conversation, thus creating a new group chat. The window for adding new users to a conversation is similar to the one used to create a new message, only one line is required to be added so as to give the group a title. For group chats, just add users to the chat. Any participant in the group can add new participants.
Group chats have some additional actions.
