DrawPen

DrawPen puts a transparent drawing layer over whatever is on screen, so you can mark up slides, code or a live demo without switching apps. A global shortcut turns drawing on and off, and single keys pick the brush, a fading pen, arrows and shapes, text, a highlighter, a laser pointer or the eraser.

Number keys cycle through colours and stroke widths, the toolbar can be hidden, and another shortcut opens a blank whiteboard for free-form sketches. Everything runs locally.
