Description

Is possible to change wind names to arrows? Or add arrow? Reasons:

1. Too complicated. You read acronym (e.g. SW) than in mind translate it into full name (e.g. south-west) than You have to remember where is west/east on a map (usually no such problems with North/South).
2. Confusing. You must clearly know that direction of wind means "from where wind come" (in weather and nautical) not "where wind go" (like e.g. in aeronautics). Arrows is obvious for everybody who use map once in life.

In any case thanks for this application - very usefull! By wind's direction I could know if gas from nearest plant will coming today.
