Convenient way to place and remove crops/trees etc

I think it would be more convenient to place and remove crops/trees with the same tool. For example you could place the crops/trees with left mouse click and remove with right mouse click.

This is kinda nitpicking on convenience since I've found myself dragging a large are to plant in a single large swipe over the map and then i would like to remove some small areas which is sometimes inconvenient because you need to change the tool.
