the alt-pg up/dwn feature to adjust brightness is pretty great. the fact that it rolls back in the morning is pretty clever, i always found myself having to fidget with settings on my monitor.
don't get me wrong, i think this needs to be fixed at a higher level to really squash the trails mac leaves on other servers (just browsing a network share leaves these behinds).
i wish more devices, like tvs, had flux baked in.
