I do not know what you think @Vitor Pamplona and @greenart7c3, but I think it would be interesting that when we use Amber as a signature device we should not be able to copy to clipboard our Nsec from Amethyst or any other client to improve security in the future and make Amber the only device that handles the Nsec, if where possible encrypted on the device.

Thank you for the great work of both.
