Disable until Sunset
I love the feature "Disable" in F.lux, since I work outdoors in the sun a lot! (Well, I love everything about F.lux :-D I'ts not a Nice2Have, it's absolutely a Need2have!)
And "Disable until sunrise" ALMOST does the job. But since I would like F.lux to work after sunset (and I just can't remember F.lux turn it on in the evenings), why don't you add an option "Disable until sunset"? :-)
Best Regards from Sweden,
P.s. I just donated 5 USD. Thanks again for a Great Service!!!! And Keep Up the Good Work!!!
