I really find it silly that this awesome image that is on the website in Materials of my tank and its used/burnt space is being wasted and not in PreForm. I would LOVE for the devs to make it so I can toggle that image on the bottom plane in preform so I can see that image under my model I am moving around. So that I can see where I should place the new model.
Even if it was a toggle and then asked if you would like to load an image. You could even just use the one generated by the website. That would be a huge feature for me personally. I hope that makes sense.
This image, loaded into PreForm, on the bottom plane, as a Toggle, so I can get an idea of where not to place the newest print:
