The "Conversations" screen (which shows a list of open chats) has always been the main screen of #Conversations_im, following the behavior of Signal, WhatsApp, and Google's Messages (SMS) app. However, after sign-up, users were taken to the "New Chat" screen (which lists all contacts and group chats) on the premise that they have no chats yet and would likely want to start one.
This may have confused first-time users about which screen is the main one.

2.19.3 has an empty chat screen instead.
