I have no doubt this plugin is programmed well, but its usefulness is severely hindered by its unintuitive admin interface.

The terminology used is quite confusing, and the inline documentation is often not complete, or incorrect. For instance, the same tooltip is repeated multiple times, or may say something like "You can translate here." I also found links to multiple different knowledge bases which conflict, are incomplete, or refer to old versions or non-included functions.

The author may want to team up with a UI Designer (and/or documentation copywriter) to improve the admin user experience.
