I'm preparing new plugin that will place hotspots automatically out of lat/long information from images.
It will have several options to play with e.g.
<gps_settings max_panorama_hotspots ="6"
hotspot_range ="25"
angle_distance ="27"
hotspot_style ="streetview"
hotspot_thumbs ="true"
arrows_up_down_enabled ="true"
north_hotspot_enabled ="true"
...
You can define max number of hotspots, minimal ange distance between hotspots, minimal range between hotspots (out of range are excluded), PGUP, PGDWON navigation to closest next hotspot, double click go to closest next point....
Current status is that this project is pending due to other urgent projects I do, but plan is to finalize it and prepare as new plugin. By the fact it is huge work already done and still lot to do, it will be comercial plugin.
