With GP, I do not have the ability — via the Customizer — to set any of the background images from the Media Library. Instead, I am only able to set an image by uploading a new one from disk or elsewhere.
This is a nuisance, because I work in the cloud from different physical devices, and because the images I need for background use are already in the Media Library.
Am I missing something?
Thanks for a wonderful theme,
Bob
P.S. — I have the full set of add-ons installed, but this does not provide the missing feature.
