It would be nice for some projects if you can say take a cube, flatten it out, then "bend" along its length it so it became a curved flat piece. Same for cylinders. Draw out a cylinder into a rod then either apply a curve to it or click on points so you can then "bend" it X number of degrees. This way you can make curved walls, curved poles for architecture, vehicles etc.
"Bendable" flat and rod like objects with an "Apply Curve" feature
