I had the hardest time figuring out how to keep my stars in the same report on the same passage. I would star resources, close the report, then re-run on the exact same passage and they would be gone.
I finally found a way. It consists in entering some information in the top section of the report that has a field for a title and one for a description (the easiest way if one does not really want to come up with something is to type a "." in the description field. It works). My guess is that a report is not saved unless something is entered in these fields. I don't know if this is the way it is meant to be or if it is a bug.
I would think that if someone stars resources, that should be registered as user customization and therefore automatically saved.
I did not find help on this feature in the help menu either.
Blessings,
Francis
