The Fusion 360 Team is all about transparency and including you in what is going on or going to happen in the future and including Fusion users in that process asking for your feedback. Somethings need updating over time, and that is not limited to wardrobes and kitchens, but also including software. Its not that that the Fusion 360 user interface and user experience (UI and UX) were poor, just that there is always room for improvement as more and more features, functionality, and workflows have been added over the years. So in the future, the Fusion 360 UI and UX will change and improve.
