When syncing photos, it would be better if it also created the folders being synced to save having to create them in Proton Drive and move your pictures to it. Also, make it a true sync so if I delete photos from my device, it also removes them from PD.

More importantly. Please preserve the metadata of the original file. It's really important to have your photos with the time and date stamp of when they were taken, and also the location information. This is crucial when restoring your files.
