As has been mentioned in comments, you can ping close voters with @-comments. See How do comment @replies work? for more info on @-comments and how to use them - specifically for your comment about not knowing how to ping a user with a space in their name.
But I can probably save you some time. Obviously I do not know with 100% certainty why all 5 people voted to close, but I am virtually certain all 5 voted to close for the same reason.
The line from the On-topic questions in the help center
software tools commonly used by programmers
is often misinterpreted to mean "recommend a tool that can do x".
While it is true that an IDE is a programming tool commonly (exclusively) used by programmers, your question isn't really about the IDE and is actually about finding an IDE with a specific list of features. While it is a subtitle difference, it is a very important one.
Recommendation type questions like this one are generally referred to as "Shopping Questions", not because you are looking to buy something, but because you are "shopping" for a recommendation.
While these types of questions can be helpful in the short term, answers are mostly opinion-based, with little content other than a link, and upvotes end up being a popularity contest rather than objective votes on the quality of the answer.
The other major issue is they become outdated very quickly. Assuming your question was open and had a several answers, if someone were to find your question 3 years from now, they are going to find a list of IDE's that is 3 years only. In the end these types of questions tend to be helpful only for a very brief period of time, so rather than dealing with out-dated shopping questions, the community decided that they should not be accepted.
