This has been resolved. Excerpt from updated readme.txt (version 1.0.2):
12/18/2012: Version 1.0.2 – Instead of creating a new custom meta box to perform this action, this plugin now adds a section to the “Publish” area of the “Edit Post” screen.
~ This update fixes the problems occurring with use of the previous versions (custom meta data and permalink information, etc. is now read/write accessible again)
~ There is now a Stylesheet file included with this plugin, jump-to-post-edit.css. Feel free to customize the color-scheme, etc. to your liking!
