I have been test driving 3.0. I prefer Gnome-brave icons. In 3.0 the restart icon is not
in the actions buttons in the panel but instead a completely different double arrows. (I can't find a image of it but it is common in several icon themes.) I have copied gnome brave and gnome common colors in to icons folder /usr/share/icons/ and tried a .icons folder in the home folder too. Neither worked. Any suggestions?
