Pix / Gthumb - Star rating

[Jopp-gh]

Generally, Mint's default apps are pretty easy to learn and help is build-in too.

Pix is Linux Mint's default photo gallery and I'd like to know a shortcut to assign star rating to images. I cant find this shortcut, it seems missing - very strange.

Adding red, green or blue flags is futile, because a bug in Pix cleans up any flags after quitting and restarting Pix.

Alternatively, where are stars written to?
Pix allows the addition of user scripts too.

I checked pix --help-all
But cant figure out how to compose my CMD to get file infos about rating:

pix general::rating /path/to/image.jpg

Lsattr would be for attributes, but stars seem not to be file attributes.
