In my node-webkit GUI plugin there are actions "enter fulscreen","leave fullscreen", "toggle fulscreen" which function properly. Haven't tested the Construct's "request fulscreen" in the browser plugin but i don't think it will work properly.
Also, i did notice some inconsistency with text-box and text object when repeatedly entering and exiting fullscreen, and re-sizing window for a few times, but i'm not sure is it just improperly written package.json or a problem with construct or node-webkit, or was i just forcing it to fall apart with fast clicking.
(actually i haven't tried fullscreen on mac, just on windows, so this applies only on win7)
Be nice until it's time to not be nice
