The magic tool icon on the proofing screen will reveal additional tools and functionality that you might like to apply to the proof. Here’s a list:
Invert pin color
Focus mode (great if you’re viewing proofs on a small screen)
Outline the proof (great if the proof has a lot of whitespace)
Ruler to measure elements on the page
Gridlines to check the alignment of artwork elements
We’re adding to these tools, but if you’d like to see a new tool - let us know in-app using our chat!
