----------------------------------------

Fabian, thanks for contributing.  Can you do me a favor and generate a new patch after moving the component to sandbox?  All of our new widgets go in the sandbox before they are voted into tomahawk.  Also, please create the patch as an attachment (instead of pasting into JIRA.)  Thanks again for your contribution.
