Woodworkerbob – carpenter cutting pattern optimizer 2-dimension Review

I am learning Google sketch up. I've built an accurate model, but not sure how to export cut list. Found this app and it works great. I type in my plywood size(4x8), then the cut sizes, and calculate button. My project will use 3.5 sheets of plywood... They even have an "image" button to show layout of what is used and what is wasted... Only changes I would suggest is: 1) being able to export the image of cuts along with list. Just a little extra to help envision project. 2) some sort of auto rotate switch. I wonder if my project could cut more waste by rotating cut list. My first list had my project on 5 sheets of plywood, after I swapped and rotated a few cuts, my waste became minimal and my project was reduced to 4 sheet(3.5 really). I wonder if there is and algorithm to find an even better fit, to reduce more waste. Another example: plywood 48"x96" and I want six cuts of 24"x30". In this order, I can get all my cuts from one sheet of plywood. If I typed it in 30"X24", the app tells me two sheets of plywood (4 cuts on one ply and 2 on second ply. Instead of all six cuts on one sheet). This should be a switch and not automatic, because some projects will require wood grain direction as part of the cut. Other than these two items, the app is superb. Good job.
