I'd suggest using a List View Web Part to display the document library instead. This will allow you to manipulate the view of the library (which, to my understanding, is what you're looking for).
- Open the document library in SharePoint Designer
- Right-Click within the
<WebPartPages:XsltListViewWebPart>
tag and select "Tag Properties"
- Click "OK" on the window that pops up. A new ribbon category should appear
- Under "List View Tools" click "Web Part" and then on the far right, "To Site Gallery"
- Click "Ok" on the first pop up window
- Then make sure to hit "Yes" on the second pop up message
The new web part will be under "Miscellaneous." You add it and can manipulate the view just like a normal document library.
