These are a couple of things that would seem to be useful, looking at the ways I manipulate data in my planning spreadsheet.
Moving Pokémon to other slots. I want to rearrange the Pokédex (primarily to put evolutionary lines in order, since unlike Gamefreak I refuse to accept №440 Happiny → №113 Chansey → №242 Blissey) which since I'm hacking Fire Red means rearranging slots.
Changing the miscellaneous breeding checks. This is primarily a convenience for the first bullet point. Doesnt provides the deets.
