Should the map include an icon for every single item, even when in a dungeon/other building? The map icons would overlap, but users could use the filter to focus on different items. It seems odd that some of the item icons are present on the map but other items found in the same location are in the icon's description, e.g. the Kokiri Sword icon with the Deku Shield and Saria's Song in its description. If a user is looking for a shield with the filter, the Deku Shield will be filtered out because it doesn't have its own icon. This also applies to items in dungeons; finding all Triforce pieces would be quite the bother, as it wouldn't be caught in the filter if they didn't have their own icons.
