- Draw lines anywhere: after closing a shape (or ending a line on an existing point or line), the next click starts a brand new line instead of chaining from the last point. - Drawing no longer stops when you close a shape. It only finishes when you right-click, press ESC, or press C.

- Multiple lines and boxes now merge into ONE clean outline when you finish, so Extrude and Hollow work on the combined shape.

- Edit Shape button: reopen a finished sketch to add more lines, then finish to merge them back into one shape. - Section Shade slider: darkens the panel section boxes so they're easier to tell apart. Set it to 0 to restore the original colour.

FIXES - Curved (arc) segments with a bulge under 1 now draw correctly and pass through the arc handle. - Ctrl+Z now also undoes a pen lift. - Start Drawing shows a message if it can't start, instead of doing nothing.
