@David-Polášek would I have also said

Customization is pretty hard to get right... Too much options tend to render apps and services complicated and unusable, which doesn't mean (as I believe) the Windy devs aren't open to add more options if it makes sense. Good idea to start this thread, to let the Windy devs find out, what kind of customizations are in greatest demand. I am sure they would implement anything that 10 % of users would find useful. So folks, what are your suggestions when it comes to custom options?

@OcchioMeteo005 Thunder is produced by the explosive expansion of heated air surrounding a lightning channel. Thunder can be heard from a maximum distance of about 10 miles (16 km) under good atmospheric conditions. When lightning strikes close, thunder has a loud clap or snapping sound. The rumbling we hear is the sound of thunder reaching us at different times from the sound produced along its length. From: http://lightningsafety.com/nlsi_info/thunder2.html
