Get path

Good module! I would suggest that you the following function to get the nid because the method you're using would be problematic if the node is aliased. I would suggest that you just have it as a local function. I think something similar needs to be in the core...

function getnid(){
	$path = drupal_lookup_path('source', $_GET['q']);
	if($path == false){
		$path = $_GET['q'];
	}
	$pathvars = explode('/', $path);
	if ($pathvars[0] == 'node'){
		$nid = $pathvars[1];
	}
	return $nid;	
}
