Not any kind of review here, but a comment. It is absolutely inane to me that I can't complete repeating todo's early.
It is a common thing for me (and I assume others) to look at your bills for instance when you have time. Sometimes when I do this I decide to go ahead and pay a bill and then ..... you know .... CHECK IT OFF MY TODO LIST.
I love the design and many aspects of things 3 (like checklists). But cmon @culturedcode!
