has anybody an idea or an advice how to analyse and sort the urls, which are not indexed?

Please right-click any workspace column to get to the workspace edit window. Leave the "group by page" checkbox empty and save by clicking "ok". Now you can sort the workspace by any column.
Likewise, you can check whether a page is indexed by selecting it in the workspace (or multiple pages, of course), clicking "update" and updating only the "cache date in Google" ranking factor.
