Thank you so much for developing these plugins, especially Curves+!
I want to request a few features for Curves+
1. A way to make vertical and horizontal curves like this much more, easier. Perhaps the ability to snap and align 2 points on a vertical or horizontal axis. Also the ability drag a segment between two points at the same time. And the ability to drag both points and segments along a straight horizontal and vertical axis with Shift+Drag key
2. Vertical and Horizontal scales. It'd be really useful to add a number scale of 0 to 100 on either sides of the curve.
3. A Preview Toggle. A way to quickly toggle the preview of the changes we make, so that we can compare the difference before and after the adjustments
