Compose Desktop tasks

Hi, I’m new to Jetpack Compose for Desktop, and need help/suggestions/documentation on a simple learning project.

In terms of UI it’s like a download manager: a lists of items, with state, and each state can lead to a task that can change the state (ie: starting, progress 0% .. progress 100%, paused, done) (the tasks can be paused too). I would like to see the state in each item of the list and have a separate view of tasks (ie: scaffold’s drawer)

Is any example project like this? Which libs can help to this tasks?

How to store the tasks, that can be managed in another view, and have a re-composition on each state change (on the visible items)?

Thanks in advance!!
