Know that there are some general problems with any rain radar:
It can be triggered by virgae and very high local humidity, so then you get an echo without rain at the ground. Also at the edge of the radar windows I have seen ghost echos.
Windy probably cannot fix these issues, so be aware of them.

It would be cool to also be able to set a wind-gust range. This is sometimes more important than the middle wind strength.

Thanks for the additional layer. I have just evaluated the predicition over the last few thermal flying days. It is always important to note that thermal predicitions are also a bit regionally influenced, so my assessment is mainly valid for the thermally weaker area in NW Germany.

What I notice is:

1. The thermal height predicition is usually overoptimistic. Often 200m below is about right. And I am already talking about the best height achieved by the best pilot of the day.

2. The thermal max. height is an important parameter, but the thermal avg. strength would actually be much more useful and better to compare.
   a) To begin with, the thermal height can be easily derived from the temp, which an advanced user will anyway look at. Thermal strength is less easy to derive without actual calculations and it is not so that high base = strong day.
   b) Over mountainous terrain always the highest peak have the best thermal max. height. They do not always have the strongest thermals though, usually the better ones, but not always the strongest. Thus the prediciton becomes a terrain map there rather than a thermal forecast there.

Speculation:
Hard to say why the forecast is nearly always overoptimistic in my region. One reason might be that ground dryness plays in reality a role in how good the ground warms up and that is perhaps not used in the calculations.
Also anything a bit closer to the see gets see wind effects, though not in all wind situations and I find the predictions also over-optimistic in south wind situations.

You can use the aerogram for that already and the color coding is used to clarify windspeeds.

I would like to set a preference with which weather model windy starts up. For my home area IconD2/EU is much more appropriate than ECMWF often.

Seconded. Windspeed without a maximum gustspeed is not usable for many Sports.

Yes, this should be configurable: Show, don't Show, only show when GPS within proximity.

@xjsch

Is that in Europe? GFS should not have much use here any more. The resolution of GFS is much lower and ECMWF also has long time prediction.

For Northern Europe ICON matches best the observed weather. D2 for short time forecasts and ICON EU otherwise.
ECMWF is a step down but otherwise second best. With Arome in France and other neighbouring countries I had mixed experiences.
