As part of taking a look at this MVP with fresh eyes (following the update to /product-roadmap ...)
I took a look at the ERD that includes lists and list-items:

Can we simulate the idea of "lists" in the UI without having/needing the lists and list-items schema? i.e. show the person their Tags with the count next to it and when they tap/click on the tags they will see all the items with that tag grouped nicely.

The only downside I can think of would be if the person wanted to share a list with a colleague/spouse and for the permissions to be applied to all the items ... 🤔
Again, I think this is achievable without needing a lists schema, because the permissions/sharing would simply be applied to the individual items.

I think I'm going to remove lists and list-items for now and if we end up needing them, we can always add them back. The UX of a "list" can still be achieved easily in the UI simply by displaying the Tags in a menu.

Thoughts?
