First of all compliments for this plugin. I just started working with it, but impressed so far.
I noticed that table names start with 'pool_' followed by the prefix as defined in the wp_config.php and then the regular table names. I believe this is not the correct order.
I have multiple wordpress installation on one domain with different prefixes for database tables, including an old one called pool. Your tables are now located between these tables.
Is this a 'bug' or is this intentional? I would prefer to start with the prefix.
