There should be a config option to disable the "download from other player" button. Making it trivially easy to duplicate someone's skin is a headache for high-profile players such as server owners and streamers.

I'd much rather distribute this mod in a modpack with a collection of thematically-appropriate skins readily available and the "download from player" button disabled by default.

In a future version I will likely add a config in modmenu. Thanks for the suggestion.
