The update I did about a year ago was designed to make the software code of Lamination PRO easier to manage. Through the years, with all the changes I made, the code got increasingly difficult and it was necessary for my own sanity to make some simplifications and eliminate a lot of redundancy. The good news is that no functionality was removed. Everything that it used to do, it still does. It just does it with fewer buttons.
Before, you had to click the Details button which then showed you the board with saw kerfs covering the entire board and it then showed you some details. By removing the details altogether, things got a lot simpler. Now, instead of pressing a button to show you saw kerfs, it ALWAYS shows you the saw kerfs. It just shows you four representative kerfs instead of a screen full of saw kerfs. The detail data that was displayed when you pressed the button now shows all of the time so there is simply no need to have the button and all of the code that went along with it.
Other changes were removing redundant buttons. For example, there were two different buttons you could click to flip or flop and other similar features. Keeping track of the state of the software was made much more difficult because of the redundancies and so I removed everything that was redundant and it made the software easier to use and much easier for me to manage.
Here is the key - if you're watching a video tutorial where the screen shows buttons that you don't have on your screen, remember that you have the latest version and that you have the ability to do everything that was on the older tutorial. Usually it means that the data is already being displayed and that there is simply no need for the now missing buttons.
