Currently we have a square plane based Populator, which is fantastic for natural work. I propose we build upon this for unnatural work such as man-made construction.
Similar to "Object to Sit On" able to to take faces of TG primitives, it would be cool to have a new mode for the Populator that works like a chain. Matching up bounding boxes of all objects in rows and columns.
It would sure make making walls, road sections, curbs, and all sorts of things a lot easier to work with than stripping down the Populator to work like you want, especially matching up bounding boxes. A warper could be incorporated for column warping, like a fence that follows the boundary of a road or something.
Just some ideas. I often want to do things like a pasture, with fences, or curbs on roads, but get discouraged by all the manual work just to start the ideas.
