Use of new play/ preview of files in dashboard

Just like Put.io and other major torrent file sharing and downloading websites offers, Zbigz should implement a new design in their file preview. For example, files should be previewed in small section of the whole file eg. 10-45sec while caching. And, when the file is cached, the online video streaming of the file quality can be changed for better connection. Another idea is that, preview+play of sound (music) should be added into zbigz and any video file from the torrent can be played which current zbigz does not obtain in their store.
