- A Mode spinbox to chose one of the modes to draw the rectangle:
- Corner, length & width
- Center, length & width
- 3 corners
- Center and two corners
- A Rounded corners checkbox to apply round corners to the rectangle.
- A Frame checkbox to add a contour with a constant offset to the (rounded) rectangle.
- All three buttons in this selection now launch the same tool but with different preset combinations of mode and options that can still be altered after the first click.
- If Rounded corners is enabled, the offset is inward, and the offset value is larger than the corner radius, the offset contour will be created without fillets.
- The modes 3 corners, and Center and two corners create parallelograms rather than rectangles.
