Fellow Composers, I really appreciate the various bits of help that you've shown me. My strategy to enter this brave new world, is to piece wise reimplement the visual parts of an existing app I maintain. I've completed my "first task" and would love any general feedback/review I could get to guide me in The Way(tm). To wit, I placed the code on Codereview (https://codereview.stackexchange.com/questions/283564/learning-jetpack-compose-tabbar-with-paging-screens). I'll attach the same source content in a thread here. Any feedback/guidance appreciated.
