There are several options you can use with trails. Some affect all trails, 

other options can be applied to a particular trail. You can change the 

way trails are updated, you can display or hide trails, make them flash, 

create a new trail, delete a trail, etc.

The options are automatic, time, or distance. When it's in the default

trail points. If a plot trail uses all of the available points allotted to it, 

the points at the start of the trail are removed and replaced by points at 

the end of the trail.
