Share only selected lists

That would be a great feature!

I think part of the problem is that "sharing" isn't really sharing between accounts. It's sharing one account. If sharing worked between accounts, we could share specific lists with certain people and not share others. AnyList works like this (but AnyList is not cross-platform, or we would still be using it). As it is, my wife and I share a grocery list, but if wanted to, for instance, make a holiday shopping list for my wife, I would need to log out and create a separate account, then constantly switch between accounts to manage different lists. Or get a second list app for personal use. Either way, not ideal.
