When Microsoft announced they were killing Wunderlist, my expectations for the New Thing were soooo low. I was spot on. Bloody hell its it's awful. Look how wunderlist works. 1. new items are added to the top 2. completed items are struck through _and_ moved to the bottom, and remain in completed order. 3. highlighted items are bounced to the top, which can then be un-highlighted. 4. items with low importance remain at the end. With _long_ lists old un-completed or permanent items migrate to the end of the list. Try a usability test with LONG lists.
