SOLUTION: Disable SteamVR start on controller power-on (or System-button press)

@Lathander

it works now. It was a bit tricky because steamVR refresh the vrsetting file when it launches.
I succeed by turned on steam VR and then wrote the line and turn on controllers and clicked button on controllers and turned off steamVR.

Armin found out that I did a mistake in the code where PE is supposed to add this line. If “power” line didnt exist in the steamvr.vrsettings, then the autoLaunchSteamVROnButtonPress line was never applied. The line was only applied if “power” : {} was already there in the file. This is now fixed and will be working in next version!
