[Request? or Bug?] Playlist listing to choose video(s) to download

[iG8R]

Is there any way to list playlist entries for further selecting which video(s) to download? E.g. I tried the following playlist https://vk.com/video/playlist/-24440848_54694294 with the Extended download... option but got only:

Extra info can't be attached due its too big size.

Since this is a playlist, you have to use the quick downloader to download the media. The extended downloader only supports one video per instance, so playlists or anything that has multiple different media sources (not formats, but like different videos themselves as an example) will cause serialization issues.

The fix I have planned is an extended batch downloader which will hopefully ease issues like this in the future, while maintaining the extended feature set.
