Changed
- The Activity feed has been rebuilt (Intel > Activity):
- Source tiles show each source's icon and how many sightings it has had in the time window. Click a tile to hide or show that source.
- A timeline covers the whole window, one bar per minute, coloured by source, so bursts and quiet periods stand out. Hover a bar for its counts; click it to see just that period.
- Each row has the source's icon and a small signal-strength bar.
- A Map button plots every sighting that carries a position (aircraft, vessels, APRS).
