Different Colour Tiers for Gratitudes
When you reach a certain amount of gratitudes (say, in intervals of 1000), the medals you get for inputting a gratitude have a different colour. (I e. At 1000, the gold medal turns to red; at 2000, it turns to blue, at 3000, it turns to green; and so on. At 10,000, maybe it turns a different colour!)
