Wunderlist is the best for me. If you would like to change wunderlist to be Microsoft To Do, please take all wunderlist's features. In this app you don't take 3 features that important things for me. 1. Login using un Microsoft account. 2. "All" task menu 3. Comment feature on each list (this point so make me happy. It used for list that I shared with another person and want to share the actual condition with a comment. Please enhance this app and I will change my rate to 5 star. Thank you:)
