Hello! 👋 I built a small player for streaming audio (Internet radio) for my own use with Kotlin and JavaFX. If you don't need yet another player in your life, maybe you'd be interested to check out a tiny DSL on top of JNA I have in the code to interact with Objective-C / Cocoa and support
"template" icons in macOS status bar. The application runs on macOS only at the moment.
