Family email address? Does that forward to all or both of you? I hobbled together a forwarding list with a gmail account set to forward auto to one of us, and the a filter to forward on a broad flag to the other, but something can skip the filter. A proper mailing list for family would be nice.
iCloud storage, Google plus, family setup so I don’t have to clean out inboxes or photo libraries too often for a family of 5. We do the Find My, shared notes, calendars and task in iCloud, but projects like vacation planing will be a Google doc since iCloud doc sharing is a bit squirrelly.
Shared password manager is key.
I would like notion, but there’s a fair bit of lockin with that format, and after Evernote I’m wary of building on sand.
