Main page progress bar
For those on level 25: Is your progress bar shooting off screen?
The same happens to me when I complete a lesson. The progress bar goes through my weekly chart. And the weekly chart doesn't show your daily score if you redo an old lesson, it only appears when you complete a new one.
The same goes for the leader-board; there's a blue bar shooting off screen as well.
Also I miss the weekly growth chart and vocabulary section... :( But other than that it looks pretty sweet.
Blue bar? Probably not, progress bar, yes. There's a growth chart after you finish a lesson.
