Want permalink editor plugin

[RonnyMac]

I'm trying to find a WP plugin which allows complete editing of the post permalink. As WP is now, the only part that can be edited in the URL string of a post is the post name portion.

Ultimately, what I'm after is a WordPress 'linked list' function similar to John Gruber's Daring Fireball site. His articles link inside to his site. His linked list titles link directly to the article on another site.

I've found a couple of plugins which do that, but as is often the case with WP plugins, updates have languished.

External Permalinks - This is almost perfect. Each post gets another field. Enter the external link's URL and it replaces the post's permalink with the external permalink. That's sweet. But also not updated for a couple of years (a habitual problem with WP Plugins-- 13,168 plugins and 24 get updated in the past year). Otherwise, perfect.

DF Style Linked List - Works for the RSS feed only. Requires a hack to do what External Permalinks does. I did the same thing for a client site in ExpressionEngine with ease. One thing I notice about WP is that much is easy to setup on the surface, but slightly more complex issues require a lot of messy mucking around.

The same thing could be accomplished with a plugin that simply edits the post's complete URL string. My searches on WP are not yielding many results. Anyone know of anything like the above?
