— is there a way to manually enter a value for the angle of a node?
It would be great to be able to enter 160° as a starting point and then move the handles to obtain a smooth curve. At the moment there is a huge amount of trial and error to obtain a whole number.
You can use a guide for that. And then proceed to find handle positions that are on the grid.
But really, the difference between 160.6 and 160.0 is negligible. There are so many other factors that will cause much bigger distortions, I have some doubts the difference is visible when the font is rendered.
