Make new close reasons dialog experience-sensitive.
I used to click "close" to vote to close things. I would get a tooltip with the reasons for closing, and I'd pick one and press enter, and then I'd be done.
Now I click "close" to vote to close things, and I get a ginourmous tooltip with the reasons for closing and paragraphs explaining each one in detail, and I have to scroll to pick the reason I want half the time.
I think the expanded tooltip is a great idea, but perhaps it should revert back to the original, shorter version for users over a certain reputation threshold, or who have cast a certain number of close votes, or are otherwise experienced enough that we can trust them to understand the close reasons.
