I've seen a few discussions on this, but thought it would be worth bringing up.
I do almost entirely print materials using your plugin. Thank you, BTW! I want my users be able to see a bleed area when editing their product to ensure that their images extend fully into the bleed, but I'd like them to be able to see a trimmed view when they preview it so it helps them better see what the product will look like when we cut it.
Essentially, it would be nice in the back end to have an option for a mask or layer that that says, "Show Layer in Preview Only."
Thanks the great plugin and the continued improvements you all make!
