Totally inaccessible with VoiceOver

This app, which would be incredibly useful for me, is totally inaccessible with VoiceOver. Except for the search field, none of the controls of the main window are accessible. They all are announced by VoiceOver as "unknown" accessibles without their text, type or other information being available to me. Im sorry, but I can only give 1 star for this lack of accessibility. And hope that this will improve in the near future!
