you can change the the zoom and height values in Config.xml. the higher the value the further distance. there are two separate numbers for zoom and for height. one is for square and one is for stage
<squarecurrentviewzoom value="1.480000" />
<currentviewzoom value="1.480000" />
is for square and stage zoom. i think 1.48 is the furthest zoom you can go with the mouse scroll. further than that like in that screenshot (8.5) has to be done in config.xml
i just uploaded a vid playing with the zoom and height. about to post it in a new thread!
