Love Figjam so far but the killer feature for me would be the ability to add freeform polyline and polygon shapes to a board.
+1 for drawing simple rectangles to help group or section off parts of the canvas, clusters of stickies etc
+1 and maybe doing something like Invision Freehand, where you can just hold option to draw a rectangle or circle
Would love be able to add chevron blocks too!
As a hack workaround, if you need a polyline of all 90º angles, you can use connectors. https://i.imgur.com/4VDsWWq.gif
