Add features to article builder WordPress plugin(repost)

I have a WordPress plugin that lets a user: * build 'authority' blog articles by including other local articles - 'subarticles' - into one master authority article. This is done using Post IDs and shortcode syntax. * * 301 Redirect each subarticle to e.g. a master article where the sub-article appears. This is done via a form in the Edit Post page. * Redirected articles no longer appear in the archives or in sitemaps (xml or html). * The plugin has a settings page with one setting, which toggles whether my client's RSS feed appears in the WordPress Admin Dashboard (similar to WordPress News). I need you to add these new features: * An 'automatic' setting where a subarticle can only be included once in an authority article, and that subarticle is automatically redirected to that authority article. * When the plugin is activated for the first time or upgraded, a red bar should appear in the Admin with a message that the user must confirm their plugin settings. I've attached a functional specification (in a zipped Word doc file) with images to explain exactly what I need in terms of how the new plugin features would be configured and used. Your work must correspond to the images you see in the Word doc. I will host the final plugin on [login to view URL], so the deliverable would be all the plugin's files in a zip file including the required [login to view URL] in the right format for wp.org. I don't require any technical docs from you, but I do need you to comment your code enough to explain any design choices you made that might not be clear otherwise. We'll talk more about that once you're on board. Please add a message with your bid that shows you have read and understood the project description and attached specification. Thank you, and I look forward to working with you.
