In the map, if you click on a tracked device, the timestamp shown will be when it last changed zone (so most likely home to away). What would be more useful would be if it showed the time of the last updated location, so you had an idea of how old that location is. I don’t need to know that the device has been away for 8 or hours or whatever, but knowing the location is only ten minutes old at a glance is more useful.
If that timestamp could be made a sensor or similar natively (I know it can be done with a template), or even just added to the attributes of the location, then even better.
