it would be awesome if when the contact information is inputted into the contact field for Textra Quick Compose feature, a thread would come up if one already exists with the contact is entered. so the message would be sent in the same thread that already exists instead of creating a new thread... Thank you..
I would live if this feature is in the next update..

another thing.. please consider adding the Chat Head feature... so new incoming messages would be easier to access instead of sliding down the notification bar all the time..
