Yes you can certainly install third party plugins if you wish, in fact we do list some of the ones we like on our
resources page. In saying this, we cannot guarantee that each and every plugin will be 100% compatible with our themes. Unless it is one of our
marketplace plugins, or a popular plugin used by many members of the community, it can be difficult to clarify if a plugin has ever been tested with our themes unless it is mentioned in our forums. Thanks.
