Be able to perform notification functions within chat body
While chatting have the ability to be able to mention an @[name] to ensure person mentioned is notified without bothering the entire group chat. Additionally if you could also perform functions such as @! or some similar kind of command that could override any snooze/mutes set by the recipients if important. The @! command could also change the color of the chat message so that it sticks out to those in the chat.
Special designations like "!" contained within a chat message might override "mute" for chats to make sure that all users get notified (woken up) if something very important is sent via TXP Chat.
