This is an amazing plugin, but it needs one tweak to work with all the sophisticated SEF solutions out there.

When you have SEF enabled on your site, Linkr will detect that but then it will generate the SEF URL itself based on (but not delegated to) Joomla's built-in, unconfigurable SEF rules. If you install one of the popular advanced SEF packages (I'm using sh404SEF), it won't work at all, and even if you just use Joomla's built-in SEF, it won't work for any article that doesn't have a menu item pointing to it.

I was able to get this extension to work perfectly with sh404SEF by manually eliminating the SEF logic from the Linkr code so that it always generates a raw url to the article. SEF solutions work in both directions, they will convert the friendly URL you put in your browser to the raw URL on the back-end, but they will also convert raw URLs back to friendly URLs *using the same set of rules* as the page is put together. It's actually safer to store the raw URL in your articles so that if you ever change SEF solutions or even just change the rules in your SEF solution, you won't have a site full of broken links as they'll all be translated according to the new rules automatically.

That being said, I still give this plugin an excellent rating since it was probably the most beneficial to our writers.
