Please review all the plugin checker results and fix the issues mentioned, if possible. These changes are typically pretty easy to make but if you have any questions just let us know.

Hi guys. Thanks for sharing this plugin with the community. You may wish to review your styles.css and check the CSS selectors so
they apply to your plugin's HTML only. Selectors like 'th#excludedheader' could affect some other plugins should they use the same
identifier coincidently. You probably want to check capabilities 'gradereport/history:view' and 'moodle/grade:viewall' in ajax.php
too to prevent eventual personal data leak.

Overall the plugin looks really good, both from UI and code point of view. Well done! With the hope these issue being fixed in a future update, you are cleared to land now. Welcome to the plugins directory!

Hi this is great. We needed this plugin for tracking compliance. The one thing I have noticed is that it is not allowing me to separate grades by groups. We have various clients taking the same training, and do not want them to see the other clients. I have sent up groups for this, but the Grade History shows everyone enrolled. I know we could duplicate the courses, but that will get unmanageable as we add more clients. Any suggestions?

Hi Laura, this plugin is no longer maintained as a 3rd party plugin as it is now a part of core Moodle.
