Marking a participant as a favourite makes them easier to spot by making them more visible on the map and also within the participant list. Your favourites save in your browser for the next time you visit the map and you can easily share them across devices.
To mark a participant as a favourite, open the Details tab and either search or scroll to find the participant you are looking for. You will see that every participant has a star next to their name. Click this to make them one of your favourites.

Once clicked, the star will become filled in and the participant name will appear in bold. On the map, their dot will be enlarged and you will see a star appear above it.
It is also possible to filter the map to only display your favourites using the filters in the Action Controls menu. And you can also share/save your favourites within this menu.
