Smart Guide for tangents to curves...
I'd like to request a Smart Guide when drawing lines for when you are over a curve and the line is tangent to a curve.

Yes please. Why is this not a boiler plate feature of a program that has been around for 20 years +????
Adobe, you need to look at professional CAD software in general. Illustrator ***still*** lacks some fundamental line-based drawing tools, like vector trim, offset, tangent detection, and so many more.
