Would be nice if when you click on the side of a shape to open a new one outside of it, it 'floats' or hovers, rather than automatically getting placed. Then you don't have to re-click and place it when you open a new one from an existing one. Maybe if you can see the other ones shifting as it hovers so you can see where it will fit in and rearrange before you place it, would be really helpful for easier visual setup and cleanliness.
