The location list box has its own context menu. e.g. you can toggle the "Hide Unselected Outside Map". The content of the location list is updated while panning or zooming the map and this menu item is checked.
It is also possible to filter locations that have data "currently available", this means there is data within their configured view period of the filter.
Filtering locations by "Somewhere available" means that there is data either within or outside their configured view period of the filter.
Filtering locations by "only doubtful and unreliable" means that only locations are visible for which there is unreliable or doubtful data within their configured view period of the filter. This can be useful when this data still needs to be manually validated.
