Apart from having half the default fields in German, I can only really see this of any use if it was part of the "Symbols"/"Symbol manager"... unless you could link fields to a specific object property (like width, height, position on page, in a group, fill, outline, number of nodes, special shape type, length, enclosing area, page it's on... etc) then you have a quick and easy customisable 'properties' page that you can see at a glance the information you want.
A method to sort/filter on these fields would be one of the major things I think is missing. Exporting the data to a XLS or even CSV would be nice as well. (instead of the "open spreadsheet" option)
