Make it so that you can use 64 keys at once. Since many people have many keys for different game modes. (For example: I have like 56 keys on Skyblock and I would join Skyblock if I used them but it would take ages). thx
No support. You do them individually so you can see everything you get. It kind of ruins the surprise if you do it all at once- at least, that's how I see it.
god please. Chests take way too long to open. It takes me 20 minutes to go through a stack of keys, which includes selloing things that I don't need.
