I'd probably have my Ryder be a bit more Starfleet about those alien burial sites, but yup, that's the sort of thing I meant.
I particularly like the idea of being able to give squadmates gifts every now and then--though, I should clarify, I'd want at most one or two gifts per squadmate, with custom dialogue for each; think the 'story' gifts, like Flemeth's tome and so on, in DA: O, rather than the miscellaneous approval-spam stuff.
But, but I love miscellaneous approval spam stuff. It's my favorite. Plus now they come with cheese! 

In all seriousness though I really like that idea. If they do gifts that should be unique and also be visible in that crew members area after the gift is given.
Taking photos seems fun. But most likely it is more "stand here, press action button and voilá, you have a professional photo added to you." 
I hope we can decide place and time for the photo. that way it is more personal and not a chore and a collection (like the bottles of thedas).
One can hope.
Oh, what if we could take hilarious selfies like in GTA 5 or like Dead Rising 4 is going to have? That would be amazing. I would even like if we could manually take our own photos in general, but unfortunately I can see it being more like 'stand here, press button' like you said.
