Make the program retry in 30min if youtube block you for a while

Hi,
1. im using your program alot and also donated. Sometimes youtube block me for just a Little while and 4K Download just skip all files and get into idle mode. If I restart the program it start download files again. Can you please add so the program retry after a while? Sometimes im gone the hole day and cant restart the program when I get blocked.

2. Can you add more options in "Intensity"? I like to download two files at the same time.

Best Regards,
Andreas Sweden
