Remove metadata in the <pre> key display area?
I'm not sure if the metadata of the key is that useful in the pre block on the keys#show view? In some display sizes it adds a scrollbar on the bottom, because the metadata is wider than the pre-block.
I think the bits of metadata of the key, that should be there, are better off outside the pre block (like the fingerprint, the email and the expiry date already are).
