Well, first of all, as the series have advanced, so should SL.
Orochimaru is long dead so I'm suggesting he is replaced with one of the following: Current Kabuto, Tobi, or edo tensei Madara.
And layouts, while I am sure that originally, the current layouts could satisfy about everyone with a favorite character of sorts, they no longer do that so I'd suggest more are added, such as one for Madara, Killerbee, etc.
Of course this is just a cosmetic and might seem of little to no importance. So It would stay a suggestion for when Neji actually runs out of things to do or for when more coders are recruited if such ever takes place.
