Zooming in and out if you play as a big batim charater and others for android

I wish you can make a zoom out and in type (now is the others) I actually want a free roam camera if you play as a charater. Second i really wish you made a run button and a walk button (the walk button is for the charaters who run even for the player). And 3rd.. how can you download docs and put them into the sandbox on android?
