Could be possible to add link to latest data on host config screen.

I've managed to do this myself, for me only, by editing html.inc.php and adding following, right after web scenarios section:

                // latest data link
                if (!$is_template) {
                        $latestv = new CSpan([
                                new CLink(_('Latest values'), 'latest.php?hostids[]='.$db_host['hostid'].'&application=&select=&filter_set=1')]);
                }
                $content_menu->addItem($latestv);

But obviously I don't know the whole zabbix coding to do this properly. Possibly hostid instead of hostids[] can be used.
