an idea about queue download

[kimycai]

how about adding "queue download" ? when we download many videos ,we should wait for the first one finished and then paste the 2nd link and download the next one,we shoud notice the download status.If we have queue download function,we just have to add jobs to queue one by one without waiting,lol.

yt-dlp accepts multiple URLs in a single run. Maybe we should allow having multiple links in the GUI?
