I like an option to have a lumberjack (Holzfäller) that is out of wood to produce a message that it is out of wood. Like the stone cutter and the mines. Since often lumberjacks are used to clean some area from trees, and then you can burn them down to make space and free the person. So it would be useful to get a message when that is the case. (Let's say when it's efficiency has fallen to 0%, to not trigger spurious messages when you have a forester around but it can't plant fast enough)
