Tangent Constraint or Advanced snapping system
I work in Illustrator all the time and I ask my self why or how can I snap a line or a shape to the tangent of another shape like Autodesk AutoCAD's "Tangent Constraint", some say that I can start with the Line Segment tool and go from there building the shape, but this option will give me a limited movement and it's not practical like if we have a tangent constraint in Illustrator so we can build logos and shapes more easier and that will make illustrator go to perfection more and more.
Since you are here, please also vote for this related request about the ability to actually add points at tangents:

Seriously. I can't believe this is not yet in Illustrator after 20 years. Basic AutoCAD like snapping is a necessity.
Besides this, you also need to be able to snap to a line extension BEFORE you drag a line out, for example to plot a new point with the pen tool that is co-linear with an existing line. I can't say how many times (probably in the tens of thousands) in my career when I have had to drag out a construction line extension just so i can start a new line that is co-linear, or at least starts co-linear with an existing line, and then delete the construction line when i am done.

I agree, and asked the same thing thing to be added as options in smart guides from Glyphs (revealed in the last Beta version available.

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.
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.
