Add feature: Change permalinks

Hi,

please add new feature to Hummingbird:

Change permalinks which cannot be changed by WordPress by default.

1) author url

http://www.web.com/author/ninja/ -> http://www.web.com/autori/ninja/

It is must-have for non-english websites.

Now you need plugin – for example https://wordpress.org/plugins/edit-author-slug/

2) page url

http://www.web.com/page/2 -> http://www.web.com/stranka/2

http://www.web.com/categories/news/page/2 -> http://www.web.com/categories/news/stranka/2

etc.

It is must-have for non-english websites.

Now I use this code snippet:

$page_newname = 'stranka';



add_action ('init', 'page_newname');



function page_newname () {

global $wp_rewrite, $page_newname;

$wp_rewrite->pagination_base = $page_newname;

}

3) hide “categories” in url

http://www.web.com/categories/news/ -> http://www.web.com/news/

Now you need plugin – for example https://wordpress.org/plugins/no-category-base-wpml/ or Yoast SEO – https://cs.wordpress.org/plugins/wordpress-seo/

4) hide “tags” in url

http://www.web.com/tags/usa/ -> http://www.web.com/usa/

Now I use this code snippet which is based on plugin deleted from WordPress repository:

/*

Plugin Name: WP-No-Tag-Base

Plugin URI: http://www.wordimpress.com/plugins/wordpress-no-tag-base-plugin/

Description: Removes 'tag' from your WordPress tag permalinks without complicated .htaccess file configurations or any other code.  Simply install this plugin and watch your "tag"-based permalinks effectively disappear.  Takes care of redirects for you as well.

Version: 1.2.4
