Allow folks to share a location along with a time window when they'll be there, as well as display a time slider on the map so that we can browser through others' future locations over time.
[x] A future location should contain the location from a location picker, a start and end timestamp, as well as a name and limited length description text.
[ ] One can set as many future locations as one likes but they can't overlap (deny or just warn in case they do?).
[ ] When dragging the time slider across the map, locations active during the current selected time window are shown in a separate style than the fixed locations from addresses.
[ ] The location layers on the map can be switched on/off to help with visibility.
[ ] The maximum time interval in the future is 1 year (do we choose that arbitrarily or is there evidence to inform the choice?)
[ ] When I enter a future location, show me who is going to be there as well in three tiers: small radius, same city, same country; and offer me to contact them via existing channels (messenger, email, call). Potentially also show me an option to join them (#34) instead of creating a separate new future location.
[ ] I would like to add future locations based on events from my calendar and pick the granularity (country, city, address).
