I'm loving the new measurement tools, including the clone measurement tools, but I was a bit surprised to see the angle presets were 45, 60, and 90. See, none of those are the angle used for cones in 5th edition D&D. A cone in 5e is supposed to be as wide at its widest point as it is long down the center line . Doing some trigonometry, that gives us an angle of just over 53 degrees at the point of origin. Thankfully roll20 has given us the option to input custom angles, so we can make 5e cones with the new measuring tools, but it's not a default option. Given the popularity of D&D 5e, I feel like it would be a good idea to include the 53 degree angle (perhaps labelled something like "5e default" so that people aren't confused as to why they're being offered such a random-seeming angle). Note that I am seeing some folks on the internet claiming that the 5e cone is 60 degrees. I'm afraid this seems to be a misunderstanding. This would be the case if the maximum width were equal to the side length, but it's actually equal to the length of the center line. You can pretty easily see the difference with the great new measuring tool. If you draw a 20-foot long, 60-degree cone on a standard 5-foot grid, you'll see that the cone is a fair bit wider than 4 spaces at the end. Try the same thing with a 53-degree cone, and it'll be (almost) exactly 4, as it's supposed to be.
