The other thing is that they can be under flight attendant control. That's frequently a good thing (dimming windows that sleeping passengers forgot to so that sunrise doesn't blast the whole cabin), but sometimes the FAs just lock them in the dimmed state, which is annoying if you actually want to look outside.
