ModernPopovers

ModernPopovers is a stylesheet that gives a new style to all popovers. This includes a redesigned user stats menu in the popovers of the chat module when hovering on the avatars and it also redesigns the reference popovers from ReferencePopups.

Code
Add the following line in your personal oasis skin stylesheet page. Since it is an import, it must be added at the very top of the page, otherwise, it won't work.
