Call me stupid, i use(d) GnuPG not to much and i'm not a pro user like
many here on the list. But when i receive(d) a signed message the first
from a user completey unknown to me i did not lsign his/her key. Instead i
verified always the fingerprint and the email headers a couple of times.

With Thunderbird/Enigmail (i can't speak for other apps) a user new to GnuPG
and and not savvy with checking email headers and not carefully checking the
fingerprint (he must click addionally on the Details button) and who has
signed a public key before would in my opinion have it easier if he would be
presented with an additional visual fingerprint imho, because he would
spot after the second email if the pub-key, he not yet lsigned, that
there is
something wrong.

If the visual fingerprint would be bullet-proof it would not hurt to
such a feature, imho.

Hope that my suggestion is not to naive or to stupid!
