The following changes have been applied to the live activity view, currently in Skyhop beta;
Only show the description of aircraft currently in view on the map
Only position information from aircraft within the map view is retrieved
The position information from all aircraft in view are updated every two seconds in order to prevent the web application from grinding to a halt on most systems.
Clicking the aircraft identifier in the right sidebar will show a list with recent flights for said aircraft
Sharing your own location is optional, and doing so will order aircraft based on those most close by
