I'm in the process of giving it a workout, but it'll have to wait for this evening. Seems real promising, though I can see how a trackball would be really useful for this. In some ways navigation is easier than I expected and in other ways it's more difficult. There's a whole slew of new shortcuts to learn and perhaps operation will go more smoothly when they become a bit more second nature. I'm thinking this could turn out to be an incredibly useful program.
