Good app, needs work.
I've been using f.lux for a few years now and for the most part I love it. It's simple, does what it supposed to do, and rarely misbehaves. However, I am growing a bit uncomfortable with the seemingly lack of innovation. New features are rare and since 'upgrading' to Win10, I've noticed an occasional 'freak out' of the screen temperature when exiting games. One feature I am most surprised is not yet implemented is the ability to create and save multiple custom profiles. So far these aren't deal breakers, but if alterations aren't made soon, I will be looking for a different app.
