How do you handle this for your own software? Could you please link me to one of your project's websites and install instructions? What specifically do you find that one OS has that's mandatory for a good/native UIs that others don't?

I hear you on the native UI is better all things considered. I'm trying to figure out how that works in practice. I.e., to accompany a "cross-platform UIs are inferior to native ones", you would be effective to also include the workflows you use. In a realm where you choose options, eliminating one should come with illuminating another, as one must choose a path, and others could be eliminated for their drawbacks as well, leaving none available. What is your path here?
