There are several channels in YouTube that are so big that 4k YouTube or 4k Video crash due to this, so it would be a good option to choose blocks to download, what I mean is, if there are 500 videos in the Play List the program should allow to pick from video 1 to 100, next 101 thru 200, etc.
Now 4k programs read the total number of videos, so "maybe" this could be allowed.
TIA.
