I just discovered the counter intuitive construction that trying to flag a question for "doesn't belong here" when you have close vote privileges is just a "long-cut" the close dialogue.
I specifically choose to click flag rather than close because I don't think the question should be closed, but in the specific case rather moved to another site. Effectively this interface just tricked me into casting a close vote.
Why is this "long-cut" in place? Surely anyone who desire to close a question would click the close link in the first place.
Edit: I don't think that I will forget that I should use the "it needs ♦ moderator attention" option for moving. This is not about helping me personally, it is about designing the system so that others may intuitively find the correct flagging option.
