Please support HideCategories="*" to hide all categories.

Please support HideCategories=“*” to hide all categories.
It would be good to do this. Then turn categories back on with ShowCategories. This lets use quickly only show few categories.

Another related issue, please support hiding categories, while also supporting CollapseCategories. I would like to only preserve properties found certain categories while also doing away with the labels.

In that sense the labels (categories) would simply be used as preliminary filters.
