I've created a nice tool with Fritz2 last weekend:
https://fluent-ai.jillesvangurp.com/
Some nice good practices for people new to Kotlin-js and Fritz2:
• uses koin for dependency injection
• uses project fluent for localization
• builds on the headless components provided by Fritz2
• easy to use abstractions for things like confirmation dialogs or busy popups that show when network traffic is happening
@Gilles Barbier also some nice examples of transitions in there.
