I'd say the same about outliners where you can't delete past the beginning of a row! Would you want to use a word processor where you had to do something special to delete paragraph boundaries?

Pages does it just like OmniOutliner. It is even more enthusiastic about deleting material — it selects the whole previous row so that you can delete the whole thing at once, none of this namby-pamby deleting a character at a time stuff!
