If you have a few tabs open, the space available for titles is limited and you can end up seeing:
recipe:meat:chick.. [Wiki] (full page path is recipe:meat:chicken:casserole)
recipe:meat:chick.. [Wiki] (full page path is recipe:meat:chicken:wings)
recipe:meat:chick.. [Wiki] (full page path is recipe:meat:chicken:tandoori)
The '[Wiki]' is really superfluous, we all know what it is. The same path in the tabs means you can't instantly see which section is being shown.
These quick mods turn the title in the tab to be just the last section of the path. There's a few places in template.php where 'name' needs to be changed to 'lastname'.
casserole
wings
tandoori
dokuwiki/lib/tpl/dokuwiki/main.php:
<title><?php tpl_pagetitle() ?></title>
dokuwiki/inc/template.php:
$lastname = preg_replace('/.*\:/', '', $name);
// default page title is the page name, modify with the current action
$page_title = " ".$lastname;
