Only the arrowhead on a windindicator/windex points into the wind. I would hazard to suggest that all met forecasts, grib files etc use the convention that the arrow points in the wind direction not in the opposite direction as per a windex. If you changed Seabreeze then it would be inconsistent and cause confusion to everyone but you.
I would like the option to customize how i see seabreeze. It allows customisation of arrow colour (red cann indicate stron/dangerous wind or no wind)
I do agree on a map it should show direction of movement, but on the graphs i am alluding to there is no background and i think it should follow wind vain conventions.
At the moment the arrow points south of the computer screen indicating wind from north. Don't get how that is logical at all.
