A-frame has a nice visual inspector tool. I would love it if there was a plugin to support UniversalAR, and show the image tracking in the visual inspector, similar to how it works on Studio. Currently I get around this with an image overlay of the tracking itself on top of the tracking, and adjusting its dimensions and position to perfectly match the real tracking, so I can see it in the visual inspector. It just helps so much with positioning the elements around it.
I hope this is feasible, thanks!
