Recently I asked a question, only to realized that the image that I posted should be cropped. Because it takes few minutes to do, I deleted a question and expected it to stay for some time (like deleted answer stays). But I was wrong - the question was gone.
Would it be a good idea add a button to temporary hide a question? (for example within the first 15 minutes after the question is posted, to hide it for 15 minutes, after which the question shows)
