Please give me a one-time option to flatten all my sidecar files directly to the Photos library

[Huw Evans]

Hello! I’m very excited about the new update and am delighted that I no longer have to manage sidecar files separately (especially for backups). However, I have ~400 sidecar files and haven’t found an easy way to flatten all of them into Photos files directly. Can you please add an option to do this; it’s too cumbersome to go through my library and individually select all of these files and run a no-op workflow on them. I’m happy to keep the app open for an extended period of time to do this bulk flattening, though.

From what they said only the sidecar files limited to adjustments will go to the library. The biggest ones that include pixel layers produced by functions such as Repair, Clone, Denoise, Deband and Super Resolution will remain separate file. So I don't think you can expect to get ride of having sidecar files in the dedicated folder, only fewer files. Just to set expectations.
