It would be so amazing if you could allow us to add a new custom field type “UI” that points to an internal Comp/Container that can then display and be interacted with on the property panel.
It doesn’t need to have drag/drop reference fields or any of the other standard properties, let the developers decide how they want to use it. Just basically drop a opviewer comp on the panel and let us figure it out from there. We can still expose variables like normal for bind/ref. Would be nice to add variable grouping and allow an arrow to show/collapse to hide the details/advanced features.
