Looking at the tutorial about the Window
https://github.com/JetBrains/compose-jb/tree/master/tutorials/Window_API, I haven't found the answer that I was looking for which is: if I start my app, resize it, close it and restart it, it does not restart with the size it used last. I assume it is something I need to implement on my own. Any suggestion on how to? Use Java
Preferences
API?
