Qt's peculiarities with which mouse events get passed where are evident here: clicking the toolbar collapses/expands, while if you're clicking the label, it has to be a doubleclick to collapse or expand.
At the moment it's my JID rather than my Name, because the NickResolver doesn't cope with our own Name.
Also: the name resizing sometimes doesn't work. If it doesn't for you, make the roster very wide and then slowly resize it down.
