Hi,Tested the new feature on Android beta and it works great, cool gimmick.
Two suggestions...
1) Some of my flights seems to only be "dotted" so maybe an adjustment for thickness or opacity could be worth considering, also to cater for differences in number of flights
2) I seems to have limitations in zooming out. Not sure if that is dependent on concentration of flights, but it was no covering a large area so maybe an issue for the ones that fly long distances.
Just my observations from first touch
