Please SuperCell, add a "+" sign in the bottom left corner of each troop in the queue in the barracks. I'm tired of having to delete half my queue to add a few troops to the front and then queue them back up.
I suggest bottom left corner to avoid accidental mis-clicks on smaller devices.
I believe he wants the capability to add more troops to the front of the queue. For example, you are training Giants, and have wizards queued after them. This would allow you to add more Giants to the queue, and have them train before the Wizards, without needing to delete the Wizards, queue more Giants, then add the Wizards to the queue again.
