Feature description

The ability to select multiple videos from history, what's new, search results, and playlists for quick actions such as download. And/or in the case of playlists, add a button to download all videos. After the selected videos would be selected for download and the download button would be pressed, the user would set the type of download and quality for all the selected videos at once.

Why do you want this feature?

Downloading music of of youtube is currently a painstaing process as each music video has to be opened, selected for download, and the type and quality of download has to be set individualy. This feature would allow an entire album to be downloaded in just one go.
