I have a new default theme. I have United Gnome Theme - Arch. I like the flat icons theme "flat-remix" that came with it. I'm still not sold to the dark theme making everything more modern assertion though. I like that it works with the Ubuntu font that I love.
United Gnome theme, Chrome browser tabs.
