Is there any preference on meta admin UI? Like a two column table with edit / delete / create?

We have the "Product Properties" feature, which is actually a key value pair. It could be similar to this. The tricky part is Array/Object values.

What do you mean by that?

That the Product Proterties UI could be an example for the Meta Data UI. But since we allow nested objects we need a way to allow this in the UI

Ok is that something Madeline should tackle, do you want to give a direction and we implement or do you want to pick that up?

I do not have resources to pick it up. Feel free to propose something that works for you.
