Ability to hide submissions from the front page is the thing I miss the most on HN. Sometimes, I'm just not interested to 10 Tesla articles or 20 Apple articles that clutter front page, but don't have a way to remove them from my view other that not visiting HN. I don't have that that articles don't belong there, it's just that I don't see any value in them.
What do you think, would you use the "hide" button if it were ever implemented?
