Bulk > Shape Style: Randomizing Colours with Rainbowify

If you want to quickly apply randomized colours to a group of lines, borders, and fill areas, Scribble Maps provides a Bulk Style Change option through the Bulk > Shape Style > Rainbowify tool. This feature automatically assigns different colours to each selected overlay, creating a vibrant and varied map appearance.
