While viewing a synth it would be nice to share information on an item. For example the synth of a town square could have links to information on some of the buildings in the synth; or simply information on various parts of an object. If this were to be a “mask” that could be toggled on or off the link could be within the current picture or for that matter on an information bar at the bottom.
A similar mask concept that could also be useful is an overlay on the Map.  The overlay of a “route” on the map in which Synths are highlighted (again perhaps with an internet link) to link synths – your own or others
