I like the idea of an app with integrated notes and todos, and love that its open source, but this is really lacking in the todo department. No drag-and-drop reordering and no deadlines/grouping by date makes it pretty useless for anything approaching a decent workflow. I've tried pretty much everything and still haven't found anything with the features/ease-of-use/good design of Wunderlist (which is still lacking in features, and has a fast approaching EOL). Considering todo apps are the modern version of hello world I would think we'd have a lot of good options (or does that reasoning actually mean there are a lot of half-baked options?)
