I've seen plenty of hiders for EA hats, outfits and items, but none for patterns. Does that mean it's impossible? I'd just like to hide the ones that I never use so that the themed and geometric sections don't take so godawful long to load.

Actually I think the reason why EA clothing and other items had a possibility to do this was because certain programs did have a 'hide in CAS' option. But I totally agree! it would be awesome if we had that for patterns. I looked around though, but I've no idea how it's done for patterns >-<
