Possible to hide rectangle color in engrave mode?

Hello,
I do a lot of worksheet for students with different layouts:

is it possible to hide in engrave mode all the green,blue…rectangle and MA,Flows…blue box information?

really difficult to do good layout with all these disturbing elements.Only the element to move or create could be enough?

Best regards

No, it’s not currently possible to hide those frame outlines, though it’s something we might add a View option for in future.

Duo: I think a good solution for this would be a key command for “preview” that would hide every non-printing element when it is pressed and held; this had come up before as a possibility for the future.
