So sometimes (often) you design something which needs more than one sheet of material. You upload sheet 1, have another inspiration and upload 20 more designs before finally uploading sheet 2, we all get distracted.
Wouldn’t it be great if you could have a folder structure or a grouping possibility so when you wanted to ‘reprint’ that somewhat ambitious table lamp or complex mechanical thingy-m-gig, everything was in the same place. Just open the thingy-m-gig group and there are you files to choose from.
In addition if you allow infinite groups then you could store all your seasonal products (like Christmas decorations) in the same place making it simple to find that design you uploaded 12 months ago.
