Show language flags at “My sites” list in WordPress admin bar. Handy with multisite installation when you have blogs with the same name but their locale would be different. With this plugin you’ll be able to see the difference between them.

Adds an extra panel to the post/page edit page which allows you to enter the META keywords & description for that page in each enabled language. Also adds an optional browser title override (does not affect post title).
Note 1: This plugin requires that <a href="http://www.qianqin.de/qtranslate/" rel="nofollow ugc">qTranslate</a> is installed and activated.
Note 2: This plugin does not work well with <a href="https://wordpress.org/extend/plugins/all-in-one-seo-pack/" rel="ugc">All In One SEO</a> and potentially any other plugin or theme which tries to set your META tags.
