I also have thought this would be a great addition to the game's menu system; would also like a description of what the marks are for the songs, foods/ingredients, pets, and treasures are. For a long time I didn't know what the treasure menu was supposed to be for. Would also love to see the list of foods in the recipe book in a certain order, like their function, or their type (loaf, cake, soup, roll, etc.). Also being able to rearrange the item list would be awesome (for the food list anyway, the others don't really need it).
I've also wondered about editing the map system so that the maps were color coded completely instead of just the jewel markers.... since some areas have more than one map. Also, the names of the places would help as well. Being able to choose where you want to go when you ride an Ancient Turtle would be a great addition, too

. Sometimes I want to go to a certain place, and I just keep riding them until I get there, but since my computer is a bit older, sometimes that takes a couple of minutes.
Happy playing
