Custom music playlists?

Yep, it works. Opened data.kfs a couple of times, found a lot of interesting things inside. Tried to create a new unit, I even extracted the files that contain the .png files inside, edited them in photoshop. When I placed the unit in one of the shops, saved the session, went into the game, the unit portrait was blank and when I entered a battle with the unit the game crashed. Also wondering on how to rename units?? Thanks for the previous answer, thanks in advance for the next one.
