We use SimpleHtmlDom in our custom theme to preprocess some elements of the dom. When activating the mobile plugin opening a page in a mobile device throws a PHP error, because of the attempted redeclaration. We probably have a workaround for this by using a multisite install, that doesn't have our theme in the mobile installation. But it would be nice if things were working without that trick. I remember there is a simpleHtmlDom module, that makes the lib available inside drupal once and for all. If mobile plugin would support it, we could change our custom theme to also use it and everything would be nice and clean. Any other suggestions?
