Hacker News Reader

Happens all the time and has been the most requested feature of all time. I like to take the charitable view and say the current design is there to let your ego explain away down votes - i.e. I am only being down voted by accident, not my post is terrible.

That feature is included with every new account!

It's especially bad on mobile, but desktop can be a problem too. I know I've misclicked a downvote on rare occasion, to my regret.
