My workaround was to call the “Post Title” the “Friendly URL” on the form, so the user would basically type in the short URL they wanted.

Then I created another text field called “Page Title” and tweaked my single.php file to display the proper/custom <h1> tag.

If you go this route, you’ll likely have to make a few modifications to your theme and wordpress core, as things like the RSS feed aren’t going to get the proper title since I’m sort of faking the result.

Hope that helps.
