I wrote a little article about my experiences with starting to play with Compose on the desktop. It's a bit rough, but if you have feedback I can use in a follow-up article, I'd appreciate it. See it here https://www.nofuss.co.za/blog/kotlin_compose_desktop_balloons/

Looks nice, thank you. Though this block

with(applyMaxMin(minX, maxX, xBool, xPos, xSpeed)) {
            xPos = this.first
            xBool = this.second
        }

is not something what I would do. Takes a while to understand what it does

Thank you, I'm open for suggestions on how to make it clearer. Would a comment help, perhaps?
