I would like to request that a confirmation screen be implemented into the username change screen. The reason for my request is because recently I mis-clicked when testing out new user names for my minecraft avatar leaving my username as "centerworl". If there had been a 'Confirm Username' tile that had popped up after I accidentally pressed enter I wouldn't have to wait 30 more days until I could change my username. Furthermore, when taking the future of Minecraft into account, I believe as the game ages and as players begin to come back, they will want to change their old usernames they had as children to something more fitting to them. Through this, I truly believe that adding a final confirmation will help prevent the unneeded anger and stress that could result from people making the same mistake I did.
