User Location and Country
Currently if you receive a chat window you do see the IP address, in practice this doesn't tell me anything to be honest. I would like to see the Country and Location (at best guess) as this will help me to understand where the visitor comes from and perhaps directly allocate this user best on his language/location to a specific user. There are several APIs that will allow you to resolve an IP to more remarkable data.
Thanks for sharing this suggestion! Definitely something we can look into!
At this moment this is not yet possible, but with a little work around, you would be able to show the chatter's browser language in the contact information:
