Can you see your tree when you make improvements to it?
If not, it would be cool, maybe for next year we can have pictures of our tree. So say after X amount of turns are put into the work for your tree, with X number of Tinsels and X number of Baubles, you can see a picture of your tree. At first there is a picture of your tree with nothing on it, but after you achieve say 30 turns put into it, with 15 gems, and 10K gold you can see your tree grow. Then another picture can be shown after 60 turns have been put into it, with 30 gems, and 25k. At the end, maybe on Christmas day or something, your final tree is shown?
