I like your ideas, they'd expand the immersion factor nicely.
I'd especially like the ability to upload and organize photos on the ship, as it'd reinforce Saira's role as a passionate photographer (though as you probably know, outside the game you can manually copy/paste images from the folder if you worry about camera memory space).
I think Nifflas meant the 'item' label only to assist players, to help us keep track of the 'quest status', so-to-speak (another term that you'd rarely see being used in real life, but that doesn't stop games from using it frequetly...
). I agree that maybe 'parts' would increase the immersion more.
However, I'm not so sure whether knowing the location of the parts would serve the same purpose. To me, the game conveys a sort of 'scavenger hunt' feeling; to build the device by whatever means possible. Knowing where to find what would go against this feeling, I think.
