Great. I would also recommend using a font which represents white spaces in equal length as widest chars in Batch I/O log window (for example, Lucinda Console does that) - this way we could see properly formatted output without the need to save them to a file first. And would also suggest to set the default "save log" name to current date and time (using legal file address symbols, and leading zeros if necessary): "year-month-day,hour-min-sec". That would help to organize logs faster.
P.S. this naming default could also be useful for "Export Grid Fields..." - we usually need to give the name some unique ID counter, and the time format serves this well.
