Use the Overlays button (top right) and List Overlays to access the overlays list. The L key on they keyboard is a shortcut.
Overlays (marks, routes and tracks) are presented in a hierarchical tree, allowing multiple levels of categories and subcategories. If you have organized your data using Categories in Memory-Map Navigator on the PC, you can save your data as a GPX file. When this file is imported into MMfA, your categories are imported too.
Checkboxes control visibility of objects on the map, or of all objects in a category
Sorting
Tap the Menu at the top-right of the dialog, and select one of the sort modes.
You can sort your data by any of the following criteria
•Name
•Date created
•Date modified
•Size of the bounding box (width plus height)
•Distance from the geographic location you are viewing on the map
•Reverse (toggles the direction of sort)
Categories are sorted by the same criteria as objects, including size, distance, etc. Creation date is the earliest creation date of the objects in the category. Modification date is the latest modification date of the objects.
Search
You can enter a search text, which causes the list to only display items that match the search string. The match may be in the category, overlay name or in the notes.
Context Menus
Right-click or Tap-and-hold to bring up the context menu on an object or on a category.
•View: takes into account all the selected objects, categories
•Move to: changes the category of selected objects. (There is no drag-and-drop or cut-and-paste)
•Import Here: Load a GPX file, placing objects within the selected category. Categories in the GPX file are ignored
•Remove Category: all contained objects are moved up to the parent category
Multi-selection
You can select multiple objects, which can be in different categories, and apply the context menu operation to objects of your choice. Note that you cannot select multiple categories, only the final overlay objects.
