XMPP Support
It will be great future which currently block our company from using tawk. We are using jabber for internal communication at it is really uncomfortable and unlogic to use another software for chat communication.
I know that you declined this suggestion twice (one had 41 votes, second 133 votes) but I think you should listen to your user's voice and not only to your's. Please leave this open so you can see how many users want the future active.
Your reasoning was that less and less IM use external integration but we are not talking about integrating with Google Talk or Facebook but about xmpp and there are many many jabber servers around and users that can benefit from this integration.

See what Olark does: https://www.olark.com/help/adium
I understand that you have some issues with an iOS app... this will solve all your problems. You can allow people to install Trillian for example on their phones and answer chat requests.
