There is no retry download on 4K Youtube to MP3

Upon files being downloaded on 4K YouTube to MP3 if the internet connection drops or there is an error.

Closing it, and reopening the program does not continue or restart any failed downloads. There should be a retry button.

Also, it does not scan the current directory to see if the files are already in there. It just downloads copies again.

Also, with the newest update, my links still are waiting to parse as the downloads prior are already done. It isn't an issue with my internet connection. Though should be an option to parse / retrieve all information before downloads start.
