If I search for Gerhard Klimeck with the search bar, I get a page of his contributions, and also a menu on the right that allows me to filter for certain types of content.  (I have a screenshot, but don't see a place to add screenshots to wishes....) 

If, on the other hand, I go to Gerhard Klimeck's member page, his contributions are listed, but there is no apparent way to filter for only presentations, or tools, and so forth.  Adding this filtering ability would be nice.
