There were numerous quirks on Windows that you just had to live with (alt-tabbing between apps when the keyboard stopped working every 10 minutes was a highlight). Changed to Figma for UI and haven't looked back. Thanks to those engineers who did work on it and gave us a non-Mac alternative to Sketch - I still miss the Repeat Grid feature.
If that falls through, and there's a very likely chance it will, they will have a serious problem.
With Flash, there was an internal hatred so deep that it's UI model for animation caught on while the abstract bezier key framing of After Effects did not in this market. They wanted it dead because they lost touch with this market. I feel like the free web-based appeal of Figma over XD may lead to the same internal agenda. Fingers crossed that I'm wrong.
