Actually, not too long ago I looked into this, turned out EWMH defines _NET_WM_STATE_FOCUSED [1] and toolkits can use this to implement such functionality. The sad thing is only GTK3 actually does this [2], so even though it's not much effort to get support for that in i3, I doubt it's worth it at this point. [1] http://standards.freedesktop.org/wm-spec/wm-spec-latest.html#id2578152 [2] It does this using an extra CSS property (:window-unfocused), so it's theme dependent Regards, Bas
