As noted below in the comments, this question specifically addresses how the functionality delivered to "complete" the supposed-Duplicate question is not sufficient, and requests a CHANGE to the designed functionality detailed there.
TL;DR I want to be able to quickly vote to keep good questions open WITHOUT having to go click through the review queue.
Currently, we cannot easily vote for questions to be left open when they have existing close votes on them - the only way to do this is to go to the review queue and click through until you find the question you want to vote to keep open. This discourages the use of "Leave Open" votes by making them difficult to cast.
There have been numerous good questions that are descriptive, on-topic, and informative for IT professionals that still manage to get several close votes. It is quite difficult for us to go into the review queue and slog through all the other questions and hope we don't burn through our close vote quota before we get to the question needing a helping hand.
And if we've already used up our close quota, we can't do anything at all until Midnight GMT to help a question out. (Note: it's possible that Leave Open uses up one of those votes. I don't know.)
I'm requesting that a 'Leave Open' button be provided in the Close Vote dialog that pops up on the questions page.
This will enhance our ability us to improve the quality of ServerFault questions in a positive and qualitative manner.
