Can I just say, that for those of you who are displeased with the new menu bar taking up too much space on your mobile, there is a mobile version of the game which is optimized for use on mobile devices. I fully understand that many people play this game on the go, I myself do as well, but for a great many things a player can make full use of the mobile version for anything that needs doing while at work or otherwise away from home.
As well, many tablets have a screen no larger than approximately 10 inches, so even with the old menu bar the screen was limited. As Richard has already stated, the menu bar will not be changed back, but feedback about it will be passed along. Before its release, this was both internally tested, scrutinized and reworked before going to the public beta server for further work. The menu bar may not be to everyone's liking, but please keep feedback to constructive criticism instead of vitriolic comments.
