The first entry in the list of software in the category "Themes and Tweaks" is the "Emeerald Theme Manager". Clicking on more info takes me to a page saying "Not found. There isn't a software package called emerald....".
Not being able to select and copy text from the software centre window made reporting this issue more painful than it could have been. :-)
