Is it a graphical buy menu and text buy menu conversion?

If so. After you get to the 1.6 screen. There's an option, then on that screen where you change your name, there's a floating box underneath the name, tap it. On the penultimate of the available options . . old is the old buy menu. It's the text purchase menu .... The first from the bottom is the left and right hand gun switch

At work now. No CS. Can't be more specific than that. When I get home from work, I'll take a look. I'll send you the exact name of the interface

This is the first time I've seen this.
