Since activities must have either laps from device or detected intervals (unfortunately we can’t have none), it would be very useful to have a bulk “Clear Intervals” option in the Activities List.
“Clear Intervals” is an action already avaliable at the Actions menu (on a activity).
Sometimes we end up with a large number of activities with automatically detected intervals, resulting in those “skyline” graphs that don’t make much sense in the calendar. Having a bulk option would make it much easier to clean these up.
