@eli, my efforts over the past week have rendered my original reply obsolete, so I’m revising this post to reflect my updated response… In short, Sudsy Page is now fully compatible with reusable elements.
In fact, the demo pages are now running the updated version of the plug-in, so be sure to check them out.
Additionally, the demo pages themselves have been updated with a real-time dashboard of URL data so that you can get a good idea of how the plug-in works…
In addition to the page itself, the plug-in is used in both the header and footer (dashboard) of the demo pages, and those are both reusable elements. Be sure to check out the blog demo in particular, as it uses both workflows and links for navigation.
