Add Metadata into video files - thumbnail as poster, Playlist as Album, and list number as track number. The program already has all that information. Please add this feature. It would make the downloads much more useable.

First of all, I love the program. Thanks for making it.

Aside from the feature to number the files, all metadata is lost upon download. Yet I see the thumbnails accompanying each video on the download list. It also knows the playlist from the 'Playlist as subdirectory' option. Its ability to number the filename means it knows the track order, which could also be put in the file. I can't find any batch thumbnail downloaders currently and I have to edit all the metadata individually if I want it to look nice on my computer. Since this program already has all the data it needs, it would be a relatively small step to add that metadata into the video file. (I checked with MP3Tag, the currently used output format is compatible with the suggested metadata - thumbnail as poster, Playlist as Album, and list number as track number) This could save hundreds of hours of work.

(If other metadata, such as user is also available, that would be nice to have that as the artist tag, but not necessarily important for organization and aesthetics)

Thanks for your time,
David
