Firstly, I wasn't exactly sure where to put this and I apologize if this has already been addressed. I looked around to see if there was a topic already and couldn't find one.
THAT SAID, I was wondering if it would be feasible to allow us to see what food we're missing for the Gourmand achievement. I was hesitant to ask since theres like 8k+ food items, but after looking through plushie collections (which are like 5k+ if I'm not mistaken?), it doesn't seem like too horrible a suggestion. With the way this feature has rolled out for book collections - that is, the missing books are broken down into multiple pages - I think it can be done without murdering the site trying to load it all.
I just thought that since other collections have this feature, it would be nice for Gourmands too.

This gets a 👍 from me every time I see it brought up and it'll continue to get 👍's until it gets implemented.
Full support for this! It would be very neat if this was implemented.
