Currently all the links in the new Closing > Off-Topic dialog open in the same window, causing an unnecessary amount of repetitive clicks and the question you're on to be replaced.
For example, if I thought the "Questions must demonstrate a minimal understanding of the problem being solved" reason was appropriate and I wanted to check out the "Stack Overflow question checklist", I would click the link and the question I was reviewing would be replaced by the checklist. I then have to click the back button to get back to the question, click the close link (again), click the "off-topic because..." radio button (again), and then click the appropriate reason.
The repetition of having to navigate back to the question and then go through the same steps to select the close reason seem like a bad UI choice, when simply spawning the links in a new tab would make much more sense. Keep the question in the current tab, open the informational link in a new tab. Seems like adding
target="_blank" to the links would resolve this. Can we get this fixed?
