I have been testing it for two days now and feel like I have been wasting my time. Way too many changes on the GUI. Very hard to navigate because they changed all the icons which are hard to see or if you change to the bigger option are way too big. Don't like what they did to the backplot. No way now to get a quick look at your toolpath. It is now just a little modified 'verify' from x7 which takes time($) to set up. I can go on but the bottom line is too many changes at once to be able to stay productive and still learn all the changes.
