In TrekMap2 Multiple Paths and Labels may overlap and stack up on top of each other. The Order of Layers panel gives you control of order in which paths and labels are layered on each other
To open the panel, either press the ⌘K key, or use the pull-down menu Edit > Order of Layers.
By default, new paths or labels are added to the bottom of the stack. To rearrange them, simply click on an item in this panel and drag it up or down to the desired location.
The panel also list the currently selected item at the top, in the gray region. Note: when a path has been selected, it will appear as the top layer while it is being edited. It will return to its correct layer when it is released.
