HI @padvincenzo

Thank you very much for your contribution! This very much looks like a feature, though. You even link to a Feature Request. There is a process how to add new features to the ILIAS core. Please have a look at our guidelines for proposing new features for the details. In this case the maintainer to contact would be Stefan Meyer. Please also have a look at the metadata of you Feature Request.

Thanks again and best, @swiniker

Thanks @padvincenzo for your contribution. I changed the release status to "Suggested for R9" I cannot accept this PR since this feature was not scheduled for Release 6/7. Furthermore I would like to refactor parts of the learning progress service before introducing more user data in the learning progress views.
