Feature suggestion:

Hi, this is a nice plugin but it would be great if there is a way for users to be able to see all their conversations(historics), even if the persons that they talked with are ofline (like the chat in FB=>you can click on a username and see your whole conversation historic with this user even if this person is not connected...) Actually you can see your conversation when the other person is online but the conversation go invisible when one of the two persons logout. Also it would be great if users have the possibility to delete their whole conversations historics with a specific person (each one would have the option to keep or delete his version of the conversation historic); It could really help to spend less disc space into the memory if the unnecessary content could be deleted by users if they want.

Thank you :-)
