My blog runs a couple of weekly features that need to retain most of the copy, categorizing, and tagging for SEO purposes. WP expects each blog entry to be "new material" and does not support the obvious solution for this need: cloning an old post to carry it forward.
This plug-in enables this, in a way the author calls "pseudo-fork-and-replace." Clone links and plug-ins appear in the UI. When a post needs to be cloned, just click, and it's done.
The author needs to document, though. The plug-in offers options to "Clone" and "Clone to Draft"--but it's not obvious to me what the difference is. By the time I go back to my post listing, I may or may not have another clone sitting in the list.
A simple bullet-list of each feature, explaining what it is for, and what to expect when it is invoked, would be enough.
