In the main site view, the bottom of the chat pane shows the room icon and has a selector for which chat one wants to participate in (I presume, as no site has multiple rooms as of yet). However, on a post page, only an avatar is shown with no selector. I get that there can only be one chat room per post, but maybe the empty space next to the icon could hold the question title, further emphasising that this chat is for the particular post? P.S. Could the drop-down be given the full width of the pane?
