Yes, the lack of a manual for that application is one of its biggest shortcomings. I've addressed that issue with them, the tech support people agree, but it won't be undertaken. Means spending money. Their help menus are close to useless. They do have some decent White Papers on their website, but it isn't a substitute for a good manual taking one through the purpose and workings of every option in the application. At least with Photoshop there's a slew of good third-party books and videos, but the clientele for this X-Rite stuff is probably too small (and the clientele for a manual smaller yet) to make a manual pay for itself. Whoever writes it will need to put in real time, so selling enough copies to recuperate the value of the time at a reasonable price would be a real risk.
