Hi Gade,
i hope i can myself clear.
if you add a custom home menu categories you can only choose a bunch of fanarts as background, but NOT only the selected category.
thats quiete a problem if you have kids. (if e.g. a background from horror apear or porno).
maybe you can add “only fanarts from this source” or something.
