Working with PolyLang

First of all, your plugin is really great!

I use the “PolyLang” for multi-language support. It works well in the desktop version; however, the title in the mobile version is not translated, and I can not find the string in the Polylang settings. How do I show different titles in different languages in the WPtouch theme? Another question: the slider in WPtouch mobile plugin should select the newest 5 posts in each language, but what it actually does to my English version is to select the newest 5 posts in ALL languages but only show the translated posts there. How should I solve this problem?
