Sometimes for planning my work, I want to see a list of items with deadlines, sorted by deadline. This doesn't seem to be possible currently. You can sort of do it with the Focus view, if items with deadlines are marked with the exclamation point and you sort manually. Alternatively, you can filter your full hierarchy of items for deadlines only, but that gives you all of the parent folders and isn't sortable. I think that a Deadlines view would be useful to many.
