Hi,

The same location - I don't see any simple way of implementing this. For example if there are two persons with a location within 100m from each other then on a zoom level of a whole city they will be showing as if they are at the exact same location even if they aren't in fact. Perhaps this is possible only by implementing a complex logic which will be grouping nearby profiles into a single location depending on a map's zoom level, but we don't have plans of implementing this complex and potentially confusing logic in the nearest future. 

More details - since the module is not tied to profiles only but shows various locations such as events, groups, etc. - it must use only data that is shared among those locations - title, pic, link. Showing more details for a certain data type entires is possible only as a custom implementation for your particular case.
