Currently in drawings only basic draft entities are available to create draft items, i.e. line, circle, ellipse, arc, etc.
Product idea is to have sketcher pallete, the same as in Sketcher module, also available for sketching draft items in drawings. This way it would be far easier to create polygons such as rectangles. Draft entities should be modifyable in a way to be able to either drag corners to deform rectangular shape and to drag sides or arcs and not to loose rectangularity (similar to *CAD Box object).
