Users appreciate the WordPress plugin for its simplicity and effectiveness, stating that it performs its promised functions efficiently and without hassle. They find it very easy to install and use, which fulfills their needs adequately. However, some users desire additional features, such as making the NIF field mandatory and having automatic validation for it, expressing concerns over the current necessity to update theme files or create a child theme to accommodate this functionality. While the plugin works well, there is a consensus that improved ease of customization would enhance its utility further.
