Hello! I think the Skyblock shop should be a lot easier to use. It takes a long time to sell cobble and stone. You have to click it, click how much you want to sell, then hit confirm. Also the numbers that you can sell, you always done have. You may have 400 stone instead of 512, then it takes you a lot more time. Also, for selling 2 pieces of cobble it takes 12 clicks. Maybe just change the shop to one like /warp shop. Maybe being able to sell some items to but all items sell for like .2 coins or something.
Thanks!
