There used to be a screen that saved your chat strings as cookies and allowed you to name them and tap/click them to re-enter but Austin got rid of it for now and wants to add it back as a native-app-only feature
He is concerned that if you save any cookies, any browser extension you have installed can read your cookies and thus compromise your privacy (e.g. by decrypting all your messages as well as everyone else's messages -- your chat strings are also your decryption key)
