One note regarding editing the number of passes: when you click on the box you get a popup with only three choices (1, 2, or 3). Overriding those choices is a little tricky - I backspace over whatever number is currently in the box, type in the new number, then left-click in the box - hitting the enter key will revert the number back to 1, 2 or 3.
