Overlay manager

The overlay manager manages all types of overlays such as points of interests (POIs) and bookmarks.

The top toolbar menu offers the following options:

Settings:
- Cluster waypoints: If enabled then waypoints are clustered leading to a less crowded map.
- Max. number waypoints: The maximum number of waypoints shown on the map for each overlay. A high value can have a significant negative impact on performance.
- Enable audio waypoint alerts: If checked then a sound is played when heading towards a waypoint with an attached alert.
- Enable visual waypoint alerts: If checked then a red warning banner is displayed when heading towards a waypoint with an attached alert.
- Default alert distance: The distance when an alert is played when heading toward a waypoint.
Check for updates: Check if there are updates available for overlays. This function works only for overlays with associated download urls.
Unload all: Unloads all overlays from the map view.
Help: This page.

- Min./Max. zoom: The zoom level range where the overlay is visible.

2. The overlay file is not used by another overlay.
Move to folder: Moves the overlay to another folder.
Clone: Create a copy of the overlay.
Redownload/Update: Re-downloads the overlay file from the webserver. This option is only available if the overlay is associated with a download url.
