I notice that when you move your cursor with an external mouse or trackpad in Orion on iPad, the cursor remains a circle and doesn’t use the “elastic” behavior where the cursor morphs into the button. I don’t know what this behavior is called exactly, but the behavior makes iPadOS apps that support it feel nice, provided that you have the feature enabled (I think it’s something that can be toggled in Settings?).
This WWDC video seems to describe the behavior better than I can: https://developer.apple.com/wwdc20/10640
As a user, I’d love to see this come to Orion as well, as it would help me somewhat in not “missing my shots” when trying to click on a button in the toolbar.
