Ideas for Planting Tool?

Let’s collect ideas people have for the planting tool, I’ll kick it off.

Would it be useful to layout plants along a polyline like we do with sprinklers?

Or something like a ‘Fill Area’ routine that fills a given areas with plants based on spacing? What does this look like, just pick a perimeter and fill it with the selected plant at it’s given spacing? Does the user have to pick the rotation?
