The scroll is very creative,but when overflows the x lines and the first line disappears,it must be an option to view the entire conversation,or else we have to go to the wlm chat window to see it.Like a dropdown menu than "slides" from bottom to top.
And one question,in the old wlm osd how you replied?Via the wlm chat or straight from the osd?
