Visualizing Semantic Data - with labels?

Below is great but it would be also great to list semantics in the OD preview:

Would you be able to give a few more details here? Do you mean something akin to a spreadsheet of prims and their semantics? Or something more integrated with the visual previews of the AOVs?

Currently its possible to see coloured bboxes in real time, but when you have a lot of them its hard to say what each color means. It wild be nice if the bbox also rendered the semantic data.
