FEATURE REQUEST: Bronze, Silver, Gold placards for language concentration success
A la angry birds, each language subject area could have different placards in the skill tree for the level of success you've achieved in each:
.... GOLD (All hearts attained)
.... SILVER (>80% of possible hearts attained)
.... BRONZE (<80% of possible hearts attained)
.... No placard (original color for incomplete)
Right now, GOLD is displayed if you've merely completed all the lessons.
