suggestion: respect folder structure
My photos are structured in folders for each year and month, just like the auto-upload-feature of the nextcloud-android-app suggests.
Many of my old photos have have created- and edited-timestamps different from the actual date they were taken but are located in the correct directory.
nc-photos can sort by date or by name. A feature to group by folders (if folders are recognized as years and months) would be great. So that, the timeline reflects the folder structure and sort by date or name only affects the order of photos of a single month. This would make a photo collection grown over many years more searchable.
