We are using arrowchat with buddypress. Right now, our users can send "standard" messages through the wordpress/buddypress messages system, or chat through arrowchat. It is complicated, and not very userfriendly.
To be able to view all messages (chat messages and "standard" messages between users) in the same place (like in FB or any other modern platform) would be a good improvement.
If Arrowchat allowed us to do that, we would be pleased to use only arrowchat for all our messaging needs inside our platform, instead of having two messaging services.
We currently use arrowchat premium (bought from another account).
Regards.
