Having a text file just like spritedata.txt, but for sound sets.
In the editor, the list could be placed in that giant empty space in the level configuration window.

OR, Just enter in the "notes" box in Sprite Database page (of nsmbhd.net) all of the compatible sound sets for these sprites, and add a feature in the editor that will make the notes appear when the mouse is over the icon. Make the post-it note (or whatever the icon is) to the right of the sprite type number?
