I've been working on an ambitious side-project for most of this year that I plan on releasing eventually, but there's no specific timeline for that yet. It's an app to develop board games, with a UI similar to IntelliJ, and a 2D-rendered "virtual tabletop" for playtest simulations. I'm keeping it closed source to keep open the potential to monetize it so I can't show you anything about it yet, but in time, as I get it in a more feature-complete state I plan on posting here to show the power of compose, and maybe release some of the widgets I've developed as standalone libraries.
I will say from my experience thus far that even though Compose is early-stage software, it is already an incredibly impressive piece of tech that is allowing me to do significantly more with UI than I would be able to with any other tech. This app is quite non-trivial is scope, but it is scaling with me incredibly well, and in general completely frees me from UI concerns because it's so easy to work with.
I have no major concerns with Compose Desktop in its current state, for either development or publishing, and see it continuing to be a great base for this project long into the future.
