Haha I have quite a bit. Dozens of analyst end users and 4-5 developers.
The thing is one day I'd like to move to Native and possibly Kotlin.js in the next gen stack.
I guess JavaFX is the best thing in the interim, especially with #tornadofx being such a powerful Kotlin workhorse for desktop apps. But I'm open to migrating off it once other options become viable. JavaFX is difficult to deploy to a large number of users, and Kotlin.js or Kotlin Native become better options in those cases.
