Not well supported

This plugin, as of 8/15/21 does not work in current version of WordPress! WordPress is thankfully regularly updated for security and stability and more, plugins expected to work continually with them should also. If a plugin built or used on a site for a hobby, that is very different that what someone should consider using as part of their everyday business site- meaning a commercial solution. For plugins effective support and updates are even more important the general functionality.
