Currently when a streamer reaches 80M sparks, when you touch the ember crystal in the app it shows the next milestones of 160M and 300M and the ember percentage bonuses for those milestones. However, there's no way to see what the current ember bonus is or even what the current milestone is that the streamer has hit. All it shows is the number of sparks that the streamer has. Unless you have memorized the spark milestones, there's no way to know the previous milestones or when the streamer has hit the current milestone. I realize this isn't a huge issue, but I do believe it is an oversight to not show the previous milestones and ember bonus percentages to see how far along the streamer has come.
Thanks for considering.
