You can zoom into the minimap with the mouse wheel and drag the floorplan around as well as resize the map box with the lower left handle.

You can now adjust the position of the panos for use on custom maps that are not proportional to the generated map.  &minimapoffset=w,h,x,y (width, height, x offset, y offset).  All values are in %.  This feature is definitely for the PROs out there as correctly moving your pano map and aligning it will take some tweaking.  If you are familiar with using your browser’s debug tools, you can fine tune by playing with the CSS and seeing the live preview as you do this.  Premium will have a GUI for this!
