Do not erase typed texts once we navigate to another window
Once we start typing in the chat window and navigate to another application or go to the previous window, typed texts gets erased and it will great if the typed texts (not yet sent) do not erase and it doesn’t need one to type the texts from the beginning.

Don’t delete text in message box when you leave the chat. Like Scruff and WhatsApp everything you typed will stay unless manually deleted.
