I tried to do some mixt styling between Arc and Adwaita, and I must say that I really like the result. It's an Arc base (flat+paddings), but with visible buttons on headerbar, the Adwaita title buttons, and the adwaita palette.
It show how could look a flat and bolder-colored adwaita, and I think that it could work kinda well xD
I'll put in on github when I'll clean a bit the code (and do better commits)
