Love the plugin! It appears that a page does not show up in the available sidebar hierarchy until it is published. Is it possible for "scheduled" pages (or posts) to appear in the structure so that you can select their sidebar prior to publishing? For us it would make more sense to be able to pick the sidebar at the time of scheduling, rather than having to go back and assign a sidebar after the page has published.
Thanks for the great plugin! Much better thought through than some of the other sidebar plugins that we've tried!
