Not sure have you noticed but I have pushed bunch of updates during the weekend which include

1. https://github.com/remdex/livehelperchat/issues/53 (change back office language in back office)
2. https://github.com/remdex/livehelperchat/issues/46 (status widgets etc. for separate departments)
3. https://github.com/remdex/livehelperchat/issues/47 (option to have operator who have access only to transfered chat and nothing else) - this one requires some article how properly do it. But functionality is there.
4. https://github.com/remdex/livehelperchat/issues/39 - (statistic global and last 24 hours) partly implemented and live

All this is live in our demo version. P.s we are laging with documentation... Regarding comming new features. If you use Live Helper Chat don't forget to danate.
