A mod for people who like variety. PackShuffle does exactly what you think it does, shuffles resource packs on certain events (launching the game or joining a world).
PackShuffle adds a small favorite button next to packs in your resource pack menu that restricts the shuffle pool. If you favorite a few packs, the mod will only cycle through those. You can also choose to ignore favorites alltogether if you so wish.
Clientside, you can use this on any server.
