You'll also just have to trust me...this product, even over the past 3 weeks, is getting more and more polished by the minute. They are up to their eyeballs in the little nuances right now.
Functionally, this thing is ready to go. I've put it through its paces (both the scanner and the editor), and for the beginner to mildly advanced tuner, they'll have no issues. I'd highly doubt even the most advanced users will have an issue. Custom histograms aren't hard to figure out at all, and everything works as advertised. I've done full rewrites, everything. No problems.
