Keep pressure isolines when showing satellite or other isolines

[koko_a]

Hi Windy team,
thanks for the great app and website!

I'd like to offer a feature, which for my opinion is missing from your app.
I'd like to keep pressure isolines on when switching to satellite / radar maps, and also when showing other isolines (such as geopotential height).
This could be really useful (e.g., plotting SLP with 500 hpa GPH, or satellite on top of SLP).

Thanks,
Koko
