I just stumbled upon a hidden tool. Why was it hidden if it works perfectly?

Shhh, transparency mask mode on the options screen is a secret to everybody!
Nobody will know it gives you the mask marker so you can draw opaque backgrounds for semi-transparent images, suitable for stickers in chat apps or sprites in games, as long as we keep quiet about it...
Whatever you do, don't clue anyone into this hidden feature, or any of the other hidden goodies and easter eggs lurking inside WigglyPaint!
