You can sort of do this with the Scatter tool, but I can never get it to place a single feature repeated along the stroke I paint. Instead, when using something like trees, I get four or five wide, no matter what I set the settings to. I could get exactly what I want by using the Single option, but it would take a long time to click, click, click along the path I want to follow. And the Along Path tool is too restrictive and slow, imo, compared to just being able to freehand a stroke and having Features "dropped" along the path by your brush.
As indicated above, a brush size could be set to determine how many Features show up along the path you create ... small brush sizes would spit out one feature wide, larger would be two ... or some such. And, of course, we would need controls for how far apart they are spaced along the path. It would be important to be able to overlap them ... or not ... as the end-user needs.
I hope I am making a bit of sense here.
