great feature to have the categories display in page titel with nice svg icons. sadly id does not handle products that are out of stock. these keep showing up as clickable categorie.
thats not really a great answer. we have over 1k products and use an import cron to place our products. when a product is out of stock it still should be available in the back-end of the shop but not in the shop display for our costumers.
so an hide empty category / out of stock function would be very welcome for this feature.
