I like: * the way it separates lists ("sub lists") horizontally, and I can switch between them conveniently with swipes, though I tend to accidentally delete tasks when trying to switch lists * I value the convenience of swipe to delete the most * being able to quick add tasks from the main screen, removes one extra tap step * being able to highlight important tasks, but wish it would automatically pin them to the top. Feature I wish most for: Image attachments. Idea: Location-based reminders?
