Version 1.0.4 brought custom edit fields so that you no longer have to remember the name of the custom fields to populate in order to create custom sidebars for your posts and pages. Version 1.0.6 fixes the custom field for the sidebar content so that it behaves within the admin edit post screen.
You can download this latest version right from the WordPress Plugin site.
There have been reports of losing the Graceful Sidebar Comment from Posts or Pages when saving posts. I’ve tested this on several instances and cannot reproduce. If you have experienced this, please leave a comment and let me know.
