Parent-controlled child tablet with approved experiences

It's a good idea but I'd prefer to have the ability to manage my daughter's account in the browser. It's a pity there's no way to filter out videos you have/haven't approved or blocked in the parent settings. There are still a lot of videos that appear from a channel I've blocked. I think it's because I approved specific videos from that channel, but there's no easy way to check. When viewing the child's account there is no search function which makes it hard to find a specific approved video.

I think there would be a BIG market for a kids tablet that parents could easily control access to. Amazon Fire tables are a disaster. iPad is too wide open. YouTube kids app is a disaster of weird stuff. Id pay a premium for this solution.
