polyline tool with 'pen' abilities

A polyline tool (that operates a LOT) like the pen in other programs but has NO ability to turn into a straight corner on the fly is really not so useful. Why can’t we shift or alt-click and get a hard point?


You can Alt+Click and this will create a Bezier handle that is broken, which will allow you to create a hard point. Alt+Click once to drag the handle on the start point, then drag again and you’ll see this.
