AeroTuner is a portable freeware application which was created as example for DWM programming article. Can be useful because. It allows you to change all DWM parameters separately without restarting DWM.
AeroTuner can change Aero Stripes amount or even disable them.
It can change colors for normal and overlayed windows separately.
Tweak the color balance, the blur balance, the aero stripes and the after glow balance, all with the help of this app.
What I would like to see in its next version, however, is a Restore Defaults button.
Best to always create a system restore point first.
