The first point is something that’s been handled by various userscripts. I do agree it should be standard, since it’s nice to try and attempt to read things for yourself before “spoiling” it for yourself.
I think I used this one?
The second… While I understand the frustration, I do think there’s value in hitting that bump in the road along the way when you screw up. The more beneficial solution long-term would be to allow yourself to be okay with making mistakes, since you will make them when using the language out in the wild too. Being able to move on after that without being discouraged is extremely valuable when you’re bound to make them a lot. But that’s just my opinion, anyway.
