The toolbar in the chat window loses buttons if the window goes below a certain size.
To me this seems like a small usability bug. An overflow menu (icon could be an arrow) would be useful to have if the window gets too small to show the icons. This would tie in well with issue #1098 as there will likely be more buttons and having access to all of them will be important.
Does this seem like something worth a ticket or a comment on #1098, perhaps?
