I find Draw.io intuitive, I like much of its tools. and the sketchy style operations make a very particular feel for a diagram. However, it is frustrating when I want a shape that is not in its library. While I can make and import them from another app, this puts those items outside the style changes that DrawIO can apply.

Describe the solution you'd like

A set of boolean set style shape operations. Select two shapes, these can be combined, joined, subtracted, or find the intersection. Use the Z-order such that the front shape is subtracted from the rear shape for the subtraction operation.

• Combining - make a single hull - intersection parts become a single part.
• Join - maybe multiple hulls, but considered a single shape with multiple hulls.
• Subtracting - Take the intersecting parts of a front shape from the parts of a rear one. Result is what remains of the rear shape.
• Intersecting - Keep only the overlapping parts of two shapes. Discard the rest.

Describe alternatives you've considered using a different package to make images and dragging them in. This takes it outside the drawio workflow, means there are additional files to manage, and only a subset of the drawio styling options can be applied.

We'll accept a PR for this one. Note the code must be security reviewed prior to being accepted.
