I like the way Fusion 360 inform users about constraints available options for selected (vertex , segment , curve) at sketch mode and I'm looking forward to finding the same feature with (constuct , axis , point )menu as i believe that tab contains hidden gems .
I think it will be great when you right click on (edge or vertex or path or face ) and find (construct , axis , point) options .
Some construct planes for example need 3points (plane through 3 points ) so when user select a point and right click, it's preferable to find a [ (2 points remaing) sentence] guide user to add 2 more points in order to use (plane through 3 points ) or select a face in order to use (plane tangent to face at point) or ... etc .
The attached image show example for more detail .
