It would be very helpful to have an option (either a second submit button, or
just a third field outright) that would provide a list of the users who have
used a given IP without showing the full recent changes display. Basically, just
an output of the usernames, the way a username check produces an output of the
IPs. When checking a user that has many hundreds of recent contributions,
scanning the whole display for a few edits by the sockpuppet becomes very
tedious and very tiring on the eyes. Several other checkusers have endorsed such
a feature.
