Did you add the futon commit by accident? thats definitely a seperate request and wont be merged until it works (I wouldnt suggest using the existing futon as a base, its not a great start)

But fixes to the performance stuff is good, that needs to get fixed just havent worked on it till the rest of the core is implemented

sorry, i add accident.
and i will see the mobilefuton

fix commit
