The brackets/braces shape is not working well for me. For one it doesn’t scale well. And the tip in the middle is barely visible, I wish it looked more like a bracket and was able to scale well. I end up using these arrows instead to create a similar meaning, but that can also be misleading and I often can’t make them look the same.
In this video I scale the brackets from small to big. I also show how I add arrows instead and try to recreate the shape.
