Not a big thing, but a simple update that shows the shortcut for closing a blip on the Done button. Also missing is the Draft check box which has been present from day one but never worked. This could mean that the ability to create drafts might be low on the priority list, or the team decided that it was confusing to have non-functioning interface elements available. Either way, it’s a sign that the Wave team are serious about cleaning up Wave and making it less confusing for new users.
