The first thing I needed to do was find out what the three graphical displays in the right column of the main screen meant. For this, the Help function was sufficently enlightening. But then I thought, "Why do I need to access Help for such simple explanations?"
There is plenty of space beneath each graphic (or top-left and -right for the direction indicator), and I imagine it would not be too hard to add very simple legends explaining what the different colours mean, just like is done for the graphs. A short coloured line segment (coloured triangles for the wind direction) with a few words next to each ("10-min av", "10-min gusts", etc) would impart enough understanding for most people, even novices like me!
One more suggestion... For me, apart from the main screen, the most-used display (so far) is the graphs. It would be great if, like EasyWeather, there was a button specifically for opening the graphs window, to save having to go through the menu every time. There appears to be room along the bottom-middle of the main window for several display icons, unless that space is used for something on some other models of AWS.
Nevertheless, a great product, Steve, thanks.
