I have another suggestion: being able to make a flexible net. I mean parts like these. I imagine something in the same way as current flexible parts, but with 4 end points (the 4 corners of the net) and points in the middle to make it a 'valley' shape or a 'hill' shape.
Ok, it might be quite difficult to make and it's probably a bit of a 'niche', but it would be nice to have nonetheless
