is there something like a SplitPane (having a UI handle resizing width/height of neighbour components)?

We implemented non-ideal version of it here: https://github.com/JetBrains/compose-jb/blob/9e67cfc916f696220d630ceb6e5b67e957077[…]commonMain/kotlin/org/jetbrains/codeviewer/ui/CodeViewerView.kt But there are issues with this implementation (https://github.com/JetBrains/compose-jb/issues/148) P.S. I think it is good candidate for custom component: https://github.com/JetBrains/compose-jb/issues/334

hmmm, so better to wait a few months and see what is there then, might be a good idea 😉
