Description

Current version only allows "Display reduce after 120 seconds maximum". Please increase to something about 10 minutes at least. I'm using this on a All-in-one desktop, power saving is not the issue but I like to reduce the display on inactivity anyway. Reading documents reducing the brightness after 2 minutes is a bit inconvenient.

Version: 1.6.1
