Passcode - Very Important

Yes, what happened to the passcode and sending files? I also want to be able to turn off read receipts. The old text message verification was much better than comparing the fingerprints. And the list of current text conversations are not color coded so they all look alike. I want to be able to choose colors to associate with my contacts.
The grey text on grey background is not good. I remember the previous color scheme being much better. The flame color is also just a shadow of its former self.
