Cleans up beautifully

I personnally use the Pro verion, because I want to get rid of orphan elements (and see them before, to make sure I don’t delete something required), but I use this plugin on every site I create.

I helps clean things up and keep the database lighter, and therefore the site faster.

Easy to use (always do a backup first!) and you can also schedule a regular maintenance (not sure if it’s just in pro though).
