Ivo, the 5.0 is really a lot faster! Good job!
On the previous version the "timeline"would stop when all data is not completely loaded and continue after complete load. This was very handy on slow internet connections. I live in the middle of nowhere (10 to 100 kbps) and work offshore (sometimes only 0.5kpbs).
Although 5.0 loads faster and more efficient i do find i miss some frames when playing trough the wind or rain forecasts.
