This is a big update! You can now connect with other households by sending a connection request on the profile page.

Why? You can now also set the visibility of events to either private, household, or network. Private means it will only show up on your calendar view. Household is the default, and means it will show up for everyone in your household. Network means it will be visible to any other households you have connected with. In the future, you will be able to share in a granular manner, with specific users or households.

There are also a few other improvements and bug fixes.
