Also on line #705 – 706
$page_title = apply_filters(“cms_tree_page_view_options_page_title”, __(‘CMS Tree Page View’, ‘cms-tree-page-view’));
$menu_title = apply_filters(“cms_tree_page_view_options_menu_title”, __(‘CMS Tree Page View’, ‘cms-tree-page-view’));
it is better, because it load translation via PO file
and line #722
<h2><?php _e(‘CMS Tree Page View’, ‘cms-tree-page-view’); ?> <?php _e(“settings”, ‘cms-tree-page-view’) ?></h2>
Thx
