Only Bedrock players who played since Summer event of 2018 will remember that the loot menu used to have more options and look like this (pictures below), there are a few cosmetic types missing: hats, gadgets, wardrobe, arrow trails (already suggested it), and shield designs (not officially on bedrock yet). I would like to see them added to bedrock some point in the future. Credits to @ElGera16 for the images
