Rubber Band Preview for Pen Tool? Curvature Pen tool equivalent?

I’m new from Illustrator and I am missing a few features - primarily the “rubber band” visual which allows you to see the path you’re drawing as you drag the cursor to a new point. Also I was wondering if there was any plugin which turned the pen tool into something like the curvature pen tool in AI - where it by default puts down curved nodes instead of corner ones? Thanks!

Glyphs works differently in this regard to Illustrator. Click to add a straight segment; click and drag to add a curved segment. This is also why a rubber band preview would not work in Glyphs: Illustrator defaults to adding curved segments, but since in Glyphs a new segment can be either straight or curved, there is no single segment to preview as you move your mouse pointer.
