@herf Was this ever accomplished? It'd be real neat if it was. Loving the functionality now, but agreed that having to run back to my computer to completely disable F.Lux to do the cool things with the Hue lamps is kind of a bummer. Alt+End doesn't seem to temporarily disable Hue control, just my monitor, so the only workaround I've found so far is to disable the entire program and restart it when I'm done.
