Shoutbox

Hmm... This could be a solution. But the flexibility is still limited. Besides, to list the convo tabs at left is not as nice as listing them on top also, since there'd be a big space below the list if the list is short.

So, if possible, I think scrolling could make the whole thing more lively, provides higher flexibility.

Btw, wat do u mean by directly switch the convo wif taskbar menu?
