I collaborate with my wife on a single family budget, so we can see total spend/income and properly budget for our household. We have a number of joint or personal accounts and credit cards. The accounts view is a bit messy. It would be nice to be able to tag accounts by the specific owner/collaborator (or possibly as joint), and display a small badge next to them. For example, we may both have the same Chase credit card, so this would be a nice way to differentiate between the accounts without having to write it into the display name.
