I've been using the "easy-todo" package, and looked at the "todo" package, for making todo lists automatically. They allow you to write a \todo{<todo text>}command, which will both show in-text and be aggregated into a todo list.
But these packages don't allow you to specify how important or urgent a todo is.
I would like a todo package that allows you to say: \todo[2]{<todo text>} -- where 2 is the "importance" of this todo.
Then the todolist should automatically order the todo items according to importance.
Does this exist?
