Jetbrains working on it. Its not easy because how layoutlib, Android Gradle plugin and Androidx things work in Intellij/IDE setups. Similar problem that Bazel not having preview working either. Its not decoupled tools can easy inject in a plugin.
I understand the frustration, also want Live Preview in commonMain. Even if its Android preview I dont care as long as working with jetbrains resources library (that doesnt work in androidMain today, like loading images.
I do understand its complex but have hopes Jetbrains solves it.
