i only find a shortcut for disabling for an hour or until sunrise. so i want to turn it on by shortcut when my eyes get tired or irritated and turn it off with pressing the same short cut again. please make this option available.
for general feedback i want to say that i find the ui very unclear. i find it hard to figure out what this is all about and where i have to go to achive what i want. maybe just me.

thanks
