"Are you sure?"

Dont you hate using the quick way to train troops by pressing the arrow key to switch between each barracks and the spell factory, but when removing troops from the que you remove a spell instead? well im putting the idea forth of havint an "Are you sure?" button for when removing spells from the que, as I have accidently removed them time after time and having to wait 30-45 minutes for spells to be made again.

You're the only one. And if it's happening to you a lot, stop and think. This should be something that happens once in a blue moon if you either focus or stop and think about what you're doing.
