❶ Live Shapes
Starting with Photoshop 22.0, you can find and control Live Shape Properties on canvas and on the Properties panel. It's really handy being able to resize, rotate, and round corners directly from the canvas.
❷ Triangle Shape tool
We have added a Triangle tool to the shape group in the Toolbar to make creating triangles much easier. You can even round the corners in seconds by clicking on a corner rounding point and dragging towards the center of the shape. All three corners will become rounded when you drag one rounding point.
❸ Line tool
You can now use the Line tool to draw a two-point line. Simply adjust the width of your line using the Stroke options.
