Hello John vers 62

The loading of a new gpx file for a journey lets say 5000 km lasts 10 minutes or longer. The search for the pois lasts forever.

Proposal load the file with all tracks deactivated and lead direktly tobthe tracks folder and let me search which track should show up.

When searching for poi first let the code check which maps are concerned and then search only in these maps.

These two measures should make it much faster.
