Edit Translations From the Admin Bar (WPML)
Adds a "Translations" menu to the toolbar on single posts and pages with a link to edit each language version, so editors can hop between translations without searching.
Snippet Library
Multilingual snippets for WordPress
Snippets for multilingual sites: language switchers, translated strings and per-language behavior with WPML, Polylang and similar plugins. For sites that serve readers in more than one language.
Polylang hreflang: Set Which Language Is x-default
Adds or replaces the x-default hreflang link Polylang prints, pointing it at the language you choose so search engines know which version to show everyone else.
Remove WPML hreflang Tags From Paginated and Filtered Pages
Stops WPML from printing hreflang tags on page 2+ of archives, search results and URLs with query strings, where the alternates often point at mismatched pages.
Search Across All Languages With Polylang
Makes the site search return results from every Polylang language instead of only the current one, so visitors find content that has not been translated yet.
Set a Different Language for Individual Pages
Adds a "Page language" box to the editor so a single post or page written in another language gets the correct lang attribute (and text direction) for screen readers, spell checkers and search engines.
