As you can see, the result is far better, but still not perfect. Believe me, this thick works for ALL core components and SOME of optional add-ons. If you want better control over your URL's - especially for the ones generated by third party components - enter the
Install and configure a specialized SEF URL manager. We recommend - and use - sh404SEF. The result is like this:
Compact, good looking, tailored to my needs (and taste), and highly Search Engine Optimized. Go for it!
