Similar issue here. I love it but it starts too early and clicking the "turn off for a hour" setting all the time was just a pain. I like that it initially tries to auto-tune itself, but I'd enjoy it even more if it had a customizable schedule.

And this might defeat the purpose, but if I could configure it to know what Spaces it was in in OS X, I could still design and not have to turn it off manually for just that one Space with the browser window in it, where knowing the actual colors is important.
