Sync between devices

### Synchronize current project between devices It would be great if we could start a project (ie multiple scenes with images) on one device and then hand it off to another device. ### Use Case I often start an edit on mobile, then want to refine it on a bigger screen or vice versa. ### Important Considerations Image privacy and avoiding redundat storage costs is super imporant so saving images and user data server-side is not the way to go. Instead, we should establish a private peer-to-peer connection between the users devices and allow handing off projects that way. Think Apple Air Drop. That would be fast, private and cost effective. This feature can be added to the app free of charge because there would be no added storage and data transfer costs which is ideal from user perspective. #### Based on [feedback: 120635]
