5 years after acquiring Wunderlist, Microsoft has still failed to replicate the great to do list manager. Critical features missing include natural language support for due dates (not available for Android or desktop), grouping of lists, and email notifications for reminders. The app has come a long way but man, what a shame it's taken 5 yrs and they still haven't even matched the old app and now they're sunsetting WL. That's 5 yrs which could have been used to enhance an already great app.
