It would be great to have the ability to sync with Android and Linux devices, along with precise control over what gets synced to each device. This could include options like syncing specific subfolders of existing syncs to another device—for example, syncing /Photos/Phone/DCIM directly to your phone’s DCIM folder. Additionally, a feature like a denylist could be implemented to prevent certain files, such as those marked with *.deleted, from being synced, ensuring deleted photos don't get transferred.
