Horizontal scrolling in Final Cut Pro X is much improved in this beta from the current release software out right now. There is still one major issue remaining. When scrolling left and right in the timeline, it moves with an inertial scrolling behavior. Before it would glitch out and randomly overshoot where I wanted to scroll in the timeline. It ruined any precision I once had before this behavior was introduced sometime in 2020. The odd thing then and still now is that when horizontal scrolling in the media browser there is no inertial scrolling behavior, only in the timeline. I've had numerous editor friends mention the same issue. So as I said, this feels much improved, BUT, I would love to have the option to turn this inertial behavior off completely. Give us that option please. Again, it feels much better now, but I'd love the option to have and try both and see what works best for me.
