6 years ago I know, but this will be very hard, as the current App just throws away all state of a chat, and later when entering starts loading eversthing again :) but we keep it for v3.
When navigating among different chats, it would be useful to have a bookmark automatically set for every chat being closed, in order to be able to follow the discussion from the exact point at which it has been left before. This is a feature implemented in the official Telegram app.
