I simply modified a vector eraser, it is not the exact same eraser as whiteboardfox's but it works close enough. I hope you guys enjoy ^-^
How to use:
1. Create a vector layer and draw on that layer
※You can use any type of brush to draw, it doesn't matter. However, for full whiteboardfox experience I would suggest pyrosnek's whiteboardfox pen.

2. That's it. Enjoy! >w<
