I appreciate your suggestion, but let me clarify a bit more to ensure we're on the same page. The issue isn't about where my camera photos are stored or how to archive albums. It's about the integration of shared album photos with my personal photos in the main view.
Here's a more concrete example: Suppose I go on a vacation with my family and create a shared album for us all to contribute our photos. I add my photos to this shared album. Now, while it's important for me to have my own photos in the main view (because they are my personal memories), there's no need for the photos contributed by other family members to mix with mine in the main view.
In essence, my own photos should appear in the main view as usual, but the photos from the shared album (added by others) shouldn't clutter my personal photo stream. This separation is something Google Photos does well, and I was hoping for a similar functionality in the app. This way, we can have a clearer organization: personal photos in the main view, and shared album photos accessible but not mixed in.
Hope this clarifies my earlier points!
