So, you have a project, at first it’s just a few tasks, all as individual tasks on a list titled “Urgent” for example. but whoa, after some thinking, suddenly there’s 30 tasks that need to be done on this project - and now it makes more sense to have it as a checklist instead of overwhelming the other urgent tasks on your urgent list. Besides manually recreating the items - there doesn’t seem to be any good way to reorganize things from “Lists” <-> “Task” <-> “checklist item”. There should be an easy way to make a task into its own list, a list and its underlying tasks into a task and a set of checklist items, or even to drag and drop a task onto another task to convert it to a checklist item. This would make reorganizing larger projects much much easier.
