Storage / Saving OSD setup?

Help / Getting Started
1

I have configured my screen by using the OSD widget (GitHub - OpenHD/QOpenHD: QOpenHD App). Is the OSD setup stored somewhere on the SD card?

In OpenHD 2.0 it should be yes, it’s /boot/qopenhd.conf. You can also load/save that file in QOpenHD for Android and other platforms, it’s portable.

The folder /boot does’n contain any file. But I could find a config-file in this folder:

/root/.config/Open.HD/Open.HD.conf

But how can I save / restore or even edit the settings file?
