This is a gigantic update to Pixelmash, and it's ready for you now! Some of the new features in Pixelmash 1.1 include:

• Completely rewritten keyframe-based animation system
• Easy option for per-frame images on any layer, for hand-drawn frame-by-frame animation
• New preview window to see your animation running while you work on a frame (also great for 1:1 or 2:1 previews on stills)
• Animated components are now chosen per-layer rather than per-project
• Easier access to creating layers at the document’s pixelized resolution
• Layers now display their native resolution in the layers window
• New onion skin options for coloring and number of frames
• Dramatically increased performance when drawing with onion skinning
• Improved resolution baking options

We even made a new 30-minute walkthrough video to show how everything works here.
