Your tool gets VideoIDs and keywords as input and generate nice report as I can see from your screenshot. But maybe you can consider another mode too? Plain list of channels (their URLs) as input (without keywords) and it checks amount of alive videos on each channel, then gives detailed info on each video (views, comments, likes) and maybe compares it with previous launch. And we can see if some videos are deleted on some accounts. And - oh shit! - which accounts were suspended or interrupted.
Then it would be YT Stats Blaster
