Just over two weeks ago, I started up a complete rewrite of the Scribbls sketchpad for drawing new outcomes. Sure, the old sketchpad was working fine, but we all wanted more out of it. This new version includes, most notably, undo and redo buttons. You asked for it, so we're giving it to you. Possibly more importantly, this rewrite is a complete overhaul of the entire codebase for the sketchpad. It's been rewritten for better debugging, faster and more responsive drawing and ease of future feature additions. For the power-users, I've added keyboard shortcuts for common tasks^*:

• Keys 1-9 switch your pencil color according to the colors in the color manager. If you only have two colors, black and red, numbers 1 and 2 will switch between them respectively.
• 0 (zero) and 'e' will switch to the eraser
• 'z' will undo your last line
• 'y' will redo that undo
• 'esc' will activate the trash confirmation

* These shortcuts have changed.

I hope the new sketchpad helps us now and in the future. And as always, submit your feature requests and bug reports to us! We heart your feedback.
