I’d love to see an area on the bottom of my page that could be a blank palette with spots to drag objects to. When an object I made (a certain shape, color, edge color, size, angle, etc) is dragged there, it becomes a button to create more of that object in the future.
This would allow for faster “on the fly” work and fewer clicks to get more done. It’s also a path to getting common company-specific objects loaded for everyone within a company.
