You should be able to set a folder for wallpapers and it should auto-scan and show all pictures or videos from that folder.
There should be two folder locations, one for night mode and one for day mode.
I use syncthing-fork to sync files to the dudu7.
If I could set a folder for it to scan, then I could easily transfer files into that folder automatically when I get into the car, without having to muck around in the menu every time I want to change the wallpaper.
Also it would be great if it supported webp animations, because gif sucks. Although the fact it supports mp4 is amazing!
