Some answers in a multiple choice test will try to take advantage of a common misconception. So if you remember the misconception you’ve eliminated one of the possible answers. Knowing what ISN’T the answer can be useful in finding out what IS. – Felix Mitchell, Architect
A cool tool is anything useful that is superior to comparable items. If you think this tool is inferior suggest a better one. You are welcome to insult a tool, but comments containing insults to individual people will be deleted. Corrections of fact are always welcomed, if stated politely. Recommendations of better tools are dearly wanted and may be elevated to the front page.
