The feature

On iOS(unsure about android), in the default photo app, I can long press a thumbnail and a preview will pop up. I’d love for this functionality to come to the immich mobile app as well. It would make selecting photos to share/download/delete easier as when you’re selecting multiple photos, there isn’t a way to view a larger picture while selecting. I also would think that an alternative to long press - look at photo - move on in addition to the existing open photo - go back workflow would be a welcomed addition.
