that stinks. that was gona be awesome   

your write you cant craft stuff on os 3.1 (yet) but u can use nlaunch to switch os. it works on 3.2

You still cant craft stuff on 3.1 but it all seems to be great on anything 3.1<.
I suggest that if you have time you should add more things to make/craft. Like armor,red stone,fishin pole.
this looks like a good list http://www.minecraftxl.com/crafting-recipes/
this is  AWESOME best of luck. hope I helped
