polomi I'm on dark titlebars and light windows now, after about a year of all-dark themes. I have to agree with WetGeek that it can be hard to tell where different windows and dialogue boxes begin and end if they're all the same colour.
unrelated, here's my work setup. I don't think I'd use i3 at home but for my job it's great. (normally I'd have an ssh connection open instead of gotop but, you know)
