Day 8. Line modifiers.
These sit on top of your design without destroying the original. Stack them, reorder them, turn them off. The source file stays as you imported it.
Pen Palette assigns pens or colours to different parts of a plot. Offset nudges lines in any direction. Dashes turns solid strokes into dashed or dotted lines. Line Edit lets you skip, reorder, or adjust individual paths. Filter hides lines by colour, length, or direction. Overlay composites multiple drawings with transparency.
I built these because real plots need cleanup and colour swaps, and I did not want that work to happen outside the app.
Try stacking Pen Palette with Offset on a multi-layer design. That is how I do colour-separated plots on my A1 Mini.
