Bug 23486 added the option for patron creation and it would be great if patron modification in staff interface would also update patron's lastseen field when the update is done in cgi-bin/koha/members/memberentry.pl. Batch patron modification should not update the lastseen field because it is often used to fix information without patron's own request and patron is not therefore "seen" in these cases. For example a library closes down permanently and patrons' home library is changed to another one.
