Hello
this is a nice plugin, i agree it should be included natively in Joomla!

But, it's a pity we can't use {php}...{/php} in the description text of a section or a category ...

Also, it would be great if you stated the examples in the module admin interface
you know, the different possible uses of includePHP :
{php}code you want to execute;{/php}
{phpfile}/path/to/php/file.php{/phpfile}
{js}alert("Code you want to run");{/js}
{jsfile}http://www.mysite.com/myjsfile.js{/jsfile}
{htmlfile}/path/to/html/file.html{/htmlfile}

anyway, useful plugin !

cheers
anthony
