Comment 24 for bug 1321750

The whole point of Caffeine was to quickly enable or disable the screensaver without changing any of Desktop Environment's settings.

My use case involves Unity and Caffeine. Ubuntu Unity currently doesn't have a screensave feature, but it turns of the screen entirely. This unfortunately makes my secondary HDMI screen onto power saving, which also turns off the sound. I used caffeine to disable screen shutdown to be able to listen to music. The concept of full-screening a music app is inexistant.

The feature provided by Caffeine 2.7 is what should've been merged into each and every Desktop Environment instead of being provided by a separate widget.
