    Regarding that GNOME update, do GNOME developers just don't have any competence in UX design? That screencast is suggesting you need to click the activities button in the top left …

    Good point. So maybe browsers should make the full version the default and then add the following options for more tech savvy users (and users can set the permanent default or per …
