Line 83 in SeoTitle should also have the condition
$pageTitle === Yii::app()->name
So that just the application name is threated as default.
I beleave that condition is not there because the index page may not show "Index - Site - Appname"
But I have a simple page where the SiteController and index are mainly the only thing.
So maybe adding the condition is not the best idea. but perhaps adding an option so that the user can choose if the breadscrumbs have more realevante than the title, so that when breadcrumbs are not empty they should be used to generate the title even before checking for a default title.
