Shoutbox

This is similar to the chat feature in skype, it can store the last convo for ages and it highlights them in yellow with a message saying messages in this chat are older than x hours/days/weeks

wat if we dont want the last line to be displayed...like if we are chatting and someone comes around and we dont want that person to see wat we are writting....then we close the chat window but when the other person (who v are chatting wid) says something and the window comes up showind watever we wanted to hide!!!!
does happen wid me and my mom....
hope u get wat i m trying to say!

easy, disable the option!

or simply hope for it to have an option to show the last lines only if it passed more then X minutes since the last time message typed/received.
