Just posted a new version, which contains task/todo creation.

• Tasks without due dates: start or end the text with “todo” (“todo – walk the dog”, “todo – renew domains”)
• Tasks with a due date: no need to use “todo”, just end your text with “due”, “due on”, “before”, “by” – with a date. (“file taxes before 4/15″, “electric bill due next tuesday”)
• You can assign importance to tasks by throwing bangs/exclamation marks after your text. The more you add, the more important it is. (“todo – sorta important!”, “todo – REALLY IMPORTANT!!!”)

New version can be found here
