Unity Editor UX is used by a plethora of people to create, design and let their imaginations run wild. In the latest beta, 2019.3, more features have been added to make the experience better and more user-friendly, with Unity saying there's "more to come."
... we took a step back to find opportunities for making improvements that are less about new features, and more about the look and feel, core interactions, and workflows.
Design improvements in numerous areas of the Unity Editor UX are reflected in the latest 2019.3 beta release, with more to come soon.
Some of the listed improvements include a more "modern" look and feel, revamping the core controls and general improvements for the workflow. The whole blog post can be found here and the 2019.3 beta can be downloaded here.
