[QuakeString]

I use many GTK apps such as Inkscape, Thunderbird, Chrome, GIMP, Manjaro software center, etc. all are them very nicely share breeze theme, but I love lightly's smooth rounded corner and shadows. But it make inconsistent looking GTK apps, My request if someone with enough skill please make a GTK3/GTK+ theme for visual consistency.
