------------------------------------------------------
How to Use
------------------------------------------------------
Write either
<Category:xxx>
in the item's Note field.

If this is present, the item will be classified as a secondary category item.
The item's original classification will be automatically added, such as "Item" for items, "Armor" for armor, etc.
In addition, the category specified as "All" in the plugin parameters will be added to all items.

If UseSubItemCategory is true, when the category window is active,
you can use the up and down keys to switch the selected category to a secondary category.

 使い方
------------------------------------------------------
アイテムのメモ欄に
<分類:xxx>
<Category:xxx>
のいずれかを記述します。

記述がある場合、そのアイテムはそのセカンダリカテゴリのアイテムとなります。
アイテムであればアイテム、防具であれば防具など、そのアイテムが元々持つ分類は自動で追加されます。
それに加えて、すべてのアイテムにプラグインパラメータですべてに指定したカテゴリが追加されます。

UseSubItemCategoryがtrueの場合、カテゴリウィンドウがアクティブなとき、
上下キーで選択したカテゴリをセカンダリカテゴリに切り替えることができます。
