Wow playing with that online version(demo) it was nice on my phone! I really enjoyed the layout! I still have the old ui and 3.9 fw, I may have to try this! I see they have simplified workstation coordinates too, I would like to see after you click into one it show what one you are in! I was resetting zero for the tmt I recently did, it would have been nice to use coords
hahahha, halloween stuff, love it
You guys getting to see what Estlcam users have been seeing for years. 
You can do it with the WebUI tablet extension. I also have an extension I created that does it. Plus, a bunch of gcode senders do it. I mean it’s cool, but you can also just look at it actually being cut.
Thanks to @jhitesma
For Estlcam you can just click parts of the toolpaths and it starts from there again, if you have to pause or want to re-cut a part 0.2mm deeper. Re-set Z, click the drawn line and go again. 
But yes, you could also use your eyes, but sometimes there are too many chips. 
Is that 4.1.1 also?
Yes it is. So far, so good.
