Hello,
I find the option to display wind barbs and current arrows on the track very useful. 
But it is not so easy to get a clear picture of the specific strength at a certain point. The best thing yet is to colour the track by drift/TWS and then set the colour scale to an appropriate range:




On the screenshot from Expedition it can be seen, that the current is mostly even in one direction and that it is stronger in the deep water in the South East than in the shallow water in the North West. But the exact direction  and the exact strength of each arrow can not be displayed.


The next picture comes from the KND Race Replay of the same track:



The RaceReplay has the option to display labels with the strength/direction of the drift/TWS. Furthermore, the size and amount of the arrows can be adjusted to avoid clutter.

This would be a really useful feature to have live on the water while sailing and not just in the Replay. It would also make things easier when comparing the measured current with the current from the grib file.
