of course i think he used alot of code from moonshell but i think it's more original than modified... although i guess it's largely up to opinion too. Apps by the same author often have common attributes. for example check out his apps, DSMPlay, Cooking Timer, Image viewer, they all have the debug screen and various similarities including menus. however i think they are just using his prebuilt libraries or code or whatever. oh and obviously he is reusing alot of other code too, but so is DSMPlay (plugin system, mp3, video playback etc).
