OverloadedOrama dd9bfc1c33 Added Onion Skinning & Custom .pxo File
- Onion skinning for animations. Choose past and future steps and toggle blue-red mode.
- Custom .pxo file. If you save your project as a .pxo file, it remembers all of your frames, their layers, brush sizes, brush colors and color palletes!
- Ping-pong loop type. When the animation finishes, it plays backwards.
- Ability to import new frames in the timeline as additions, without deleting the previous frames.
