[Request] Updating or downloading Weekly series without re-downloading everything

Requesting a feature where Lyndor checks and download missing/new videos automatically. Currently there is no way do it(?) other than to re-download everything.

For the time being to download/update weekly releases, I am using youtube-dl with --download-archive option which seems to support resume as well but not the perfect solution I guess.

Do consider if it's useful. Thanks dev.
