I also liked being able to use the name of the TV instead of the id.
To do this, change the plugin from
&automaticTplTvID=automaticTpl TV ID;text;
to
&automaticTplTvName=automaticTpl TV;text;inheritTpl
and change
//find the first parent that has an automaticTpl TV and on which level
while($parent){
to
$automaticTplTvID = $modx->db->getValue( $modx->db->select( 'id', $modx->db->config['table_prefix']."site_tmplvars", "name = '$automaticTplTvName'" ) );
//find the first parent that has an automaticTpl TV and on which level
while($parent){
