This plugin adds some more Polylang support to basic widgets like Tag Cloud, Categories and Recent Posts.
This plugin add the widgets Categories - Fixed Target Language, Recent Posts - Fixed Target Language and Tag Cloud - Fixed Target Language. Polylang currently supports only listing categories (and also recent posts and tags) for the current active language. This plugin re-creates the mentioned basic widgets and adds a option for selecting the target language.
Example: With these widgets it's possible to show your english tags even if you are on a german page on your blog.
