I have idea (sory for my english but I don't speak very well)
1.quests for clan
2.option to add builders to upgrade building with higher speed (2 builders for one building)
3.new troop to take dark eliksir from enemy bases (something like a upgraded goblin from dark baracks)
4.option to change your dark eliksir ( I have 2000 dark eliksir and i can change it for 20000 eliksir or gold but not eliksir or gold for dark elisir)
