Now when you select an asset and then translate (‘g’) or rotate (‘r’) and then select an axis (‘x’, ‘y’, or ‘z’) the action happens when you move the mouse left or right.  So if you want to move something along the x axis you select it, press ‘g’ then ‘x’ and move the mouse.  Also you can save a map and load a map.  It’s saved in JSON format so it’s pretty easy to work with in the actual editor and the PHP that actually writes the file.  Still lots of work to do but I’m making real progress toward some basic functionality.
