Just the normal shop window but with a custom order instead of sorted by ID.
Maybe you know the Call Shop command from RPG Maker 2000. There the items in the shop windows were sorted by the order how you put it into the command windows in the editor.
So you could have it like this:
[1] Bronze Sword
[5] Bronze Spear
[9] Bronze Axe
[2] Iron Sword
[6] Iron Spear
[10] Iron Axe
Without rearranging the whole database.
