Don’t use your mirrors. Just turn your body so you’re looking out the back window, and everything becomes much easier. Also, make small corrections. Large corrections compound themselves and you’ll have to stop and pull forward to straighten out. — Robert Paxton, technical team lead
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.
