Copy and paste in clear text? Yes, I don't think that's a good idea. Download to disk in clear text? Yes, I don't think that's a good idea.
Years and years of security incidents with consumer data show that this is a really bad idea.
At minimum, a credential manager distributed for wide use should encrypt exported/copied keys with a user selected secret or user generated key.
