2nd monitor
Overall this is an awsome app, I found you can resolve the popup issue when using a 2nd monitor by clicking Fireplace App -> About Fireplace App, It dosent accually bring up the about page but it prevents the popup untill the next time you click on the fireplace screen. Also you can click on spaces in the dock (because the hot corners are disabled).
I would consider adding the ability to change sounds (but keep the one you have now) however it would be nice to give it a bit more of the deep roar you might expect from a fire this size.
