A preset cannot be changed inside the application.
- Edit per_frame, per_pixel, custom shapes and waves, and the warp and composite shaders, with the result live on the running preset.
- Errors point at the line in the preset, not at generated code.
- Sliders for the main values (zoom, warp, rotation, decay, echo), with a note when the preset's own equations overwrite them.
- Save as a new preset of your own; the original is never changed.
