I'm constantly cutting a straight line so I can send a road directly into a new glade by marking the path, and then switching to remove marks and clipping off the unnecessary ones. Could you add another, smaller brush button so I could target single trees?
Hey there! There already is something like this in the game. Simply hold down Shift when marking trees to shrink the brush. There are some other useful shortcuts tied to tree marking - they are listed in the tooltip when hovering over the "mark trees" button.
