I am very annoyed with the new pop up for energy in exchange for gems. I have 2 games running and I have accidentally used 5 gems on each because I don't watch my energy levels. Previously there was a "you don't have enough energy" warning but now it's one click and valuable gems lost. It's bad enough when you accidentally speed up a building because there isn't an "are you sure" pop up.
I see I'm not the first to comment but the thread has been locked off so nobody else can add their opinion.
Please re-think this from a players point of view.
