This is a frequent minor frustration, and I know it’s petty, but UX really is about everything, and little things count.
The edges of the Point on Curve component where one needs to click and drag in order to move it are very narrow. I don’t know the pixel count exactly, but they can’t be more than 3 or 4 tall. Every time I go to move one of these guys around, there’s a decent change that I’ll end up accidentally moving the slider or stretching the component. All it needs is a little more space to click on.
