Maybe there could be 2 versions of the chart up to 13000 m and 5000 m ...

RE: Windy offers Sounding Forecast
Great idea - but http://www.xcmeteo.net has been a much better display for some years (for paragliders), although unfortunately it comes from the GFS.
Paragliders and other non-powered airplane pilots are mainly interested in how powerful the thermal will be, what will be available and where the cloud base will be - and it is hard to recognize from your charts. They need to see the chart in detail up to a maximum of 4000 - 5000 m. What temperature and wind will the 13,000 m be likely to be interested in transport aircraft pilots.
