Still not done with it, but lots of new tweaks. The biggest one is the addition of Tags, as well as an update to the InputfieldPageAutocomplete (committed today) that makes it work really well for tagging. Now when you are entering something in the autocomplete, if it doesn't match anything you can just hit enter and it adds it as a new page. This is assuming that you've configured the field to support that feature. Anyway, the point of this is that it's a very natural way of adding new pages with autocomplete.
