Shared user behaviour in map view #709
Description
Is your feature request related to a problem? Please describe.
Shared user tracks are difficult to differentiate from the own track, and if there are many shared users, it's challenging to keep track of them.
Describe the solution you'd like
I suggest to:
- Display the user's track color in the user list, so that it's clear which color belongs to which user
- Show/hide user tracks by clicking on the user's avatar.
