Lacks editing features!!

Hi,
Ive just recorded my whole night but I cant reach a specific point of my recordings!! The drag function indicated just dont work! Im using the app at my iPad Mini. I have 8 hours recorded and want to jump to the middle point, but the app do not allow me to do it, my option is to listen to everything!! We should also be able to wrap out the non-talking parts, but we cannot do it! Please, add tese features urgently!
Thanks,
Alexandre
