I've noticed that the zsnexbox rom browser doesn't use the analog shoulder buttons to their fullest. In Xport's, uh, ports, lightly pulling the right or left trigger will cause the browser selection to scroll up or down, slowly; pressing it harder causes it to speed up. Implementing this, in addition to paging up and down via the d-pad and looping the browser list (Z to A and vice-versa), would make navigation incredibly badass. Something to think about, anyway.
