Reminders are delightful thing. Apple’s implementation syncs across the Mac to iPhones and iPads, and if you log in to iCloud.com, you can share Reminders with friends, family, co-workers, and the like. They’re super useful.
Sometimes, though, you might want to single out a specific Reminder for special attention. There’s really no starring system or tagging available within Reminders itself, so you’ll have to get creative.
