Add a simple sleep timer button (e.g. play the current theme for 15-30-45-60 minutes, then close the program) to the main program screen--am surprised it's not already there.

It would be fantastic if sleep timer functionality was combined with a script that would put system into sleep mode for selected number of hours, followed by a system "alarm" function that turned Halotea back on with a wakeup theme: i.e., something like Time to Wake Up followed by WAKEUP, for variable time period....

What a great way to ease back into consciousness - could ditch the alarm clock for good! Very pleased to find this program - it helps reduce some negative chronic health symptoms. It will be running whenever I need to spend long hours at my computer. Thanks so much for sharing it !!
