Hello,
it is possible in the class - webdocs a download button to integrate ?
I have PDF - files that are displayed on GoogleDocs .
In view of the above are right two buttons . Can someone still add a download button too ?

You can just add a fullimageurl link to your theme page as a download link (or using the downloadlist plugin). All file formats are "images".
