Suggestion: manage apps in preference pane
I love f.lux and I recommend it to everyone. It's very handy and easy to use, and it's great that you can set f.lux to be disabled for specific applications.
However, because f.lux only works from the menubar, and because you can only enable/disable f.lux for the frontmost application, it's not possible to disable f.lux for apps that only run in fullscreen – for example, many games.
It would improve f.lux even further if the preferences included a list where you could add and remove apps to for which f.lux is disabled, without having to launch them or have them active at the front.
Thanks for making such a great app free!
