I am a long time user and lover of Wunderlis, the predecessor of this app. And I like the new concept, I was using the old app as a to do list as well BUT there are a few things I take issue with: 1. you cannot reange the order of your tasks. 2. in every list you have to check the box: make finished tasks invisible/visible. The combination of the 2 make it impossible to stay organized. I hope they fix this stuff soon, I don't see any reason why this isn't already a feature.
