Beyond that, most things display first four & last four, so you can probably assume they have that too.
- Terr_ 11y ago> I don't see how you could salt them in any useful way Yes, I agree. Even two seconds of waiting for your search is a little on the high side, UI-wise. > Beyond that, most things display first four & last four My impression is that "only last four" is the most-common.
