Preview positions in line with Joomla 1.5

Have you been wondering how to preview module positions in-line when using Joomla 1.5?

This feature is not available in the backend of J! 1.5....

So when you next download a template, download (or print out) the given module position layout. However - you can see the module layout by adding tp=1 to the index page of any Joomla site - e.g. http://www.j-b-t.com.au/index.php?tp=1

By the way this nifty trick works on J! 1.0 sites too!
