Acorn 2
Coolest new feature:
Layered Screenshots It’s a new preference, and it’s turned off by default since it’ll make some pretty big images- but you can now take screenshots where every window gets its own layer, and the layers are organized by applications in layer groups. So now you can take a screenshot, and not worry because your background has something funky in it, or you are surfing porn in another window that accidentally got included in. Just delete or uncheck the visibility for that layer. TADA. It’s also awesome for grabbing parts of windows when you are doing UI mockups.
