What's the easiest way to create the equivalent of a grid layout recycler view currently? (not staggered) Thought of having a lazy list of column, where each line would be a row having n elements, but feels hacky

yes, it is a way to go for now. we are going to provide some out of the box LazyGrid component, but in the meantime what you described seems reasonable

Or if you don't have many items then you could use this kind of approach: https://github.com/android/compose-samples/blob/master/Jetsnack/app/src/main/java/com/example/jetsnack/ui/components/Grid.kt

Arround 50 simple items. I think this approach would be better to handle the "decorators", I want to draw the actual grid. Thanks!
