When two persons are chatting and one goes off-line..

Chat box doesn't show that the other person goes off-line..

It create confusions b/w two users...

Yes you are right. We will improve it in next version.

When the new version it coming any idea...

separating line after each message..

or difference b/w sender and reviver's name
