janneuuThe mdash in the second set of "Expanding and collapse characters" is wider than the plus sign, which is not visually pleasing. If I select "custom" and put in + and – instead, the ndash will output some Unicode mess. The Collapsing Categories plugin does not seem to have this problem.
Another thing is that if have left "Month links should expand to show posts" unchecked, the months are listed with no li characters at all. I think the plugin should, in such cases, wrap and css the months as items.
