If nothing else, this is an excellent tool to find out before you perform a synth, exactly how many progress actions (and which) you will need to reach the finish. Without it, your very first synth of an item could be a case of trial and error, which means big money if it's your first time performing an endgame craft synth that comes out NQ because of a silly mistake.

Been only using this for a month or so now, but am so glad I started, it's great! Thanks, and keep it up OP! ^_^
