Looking good! Also a much improved UX I would say. Some suggestions:
- Make sure the color icons stay visible when moving the range sliders so you only see the color swatch and the background. This makes selecting a color much easier.
- Sometimes it helps to be able to adjust the settings when passthrough is off. For instance to see if the color you selected is actually the same color as the background. Maybe there is a better way to show that the passthrough is active/ inactive without disabling the controls?
- The plus and min icons in the range and falloff sliders more often than not block slide input (as the setting is often in the extremes). If find this pretty annoying as you'll have to click more in the middle of the bar and then move back to the plus or minus icon to make an adjustment. This makes making small adjustments very difficult. Maybe you could block the plus/ minus click listeners if its a long press/ "grab"? Even better might be to be able to use a thumbstick to adjust the sliders more precisely when you hover over one. So you can make small nudges that way.
- I would argue that it would be nice to be able to enable passthrough for people that do not have a MR device so they can remove green screens. Maybe even allow for uploading a custom static background?
