The loading bar and layer counter status are the main tools currently available for tracking a print’s progress. While they are effective for getting a general sense of progress, I feel like there are much more visual and intuitive ways of displaying this information.
One such option would be to display the same view as the existing one in the preview tab, but lock the layer selection sidebar to display the sliced model matching the print progress and updating as the print progresses. No need to see exactly where the printer is at within a layer, just which layer is currently being printed. This would also make it easy to verify that the print is indeed going as expected.
A perfect place to put it would be instead of the inactive camera view. In my case (and given the low framerate), I mostly use it to ensure nothing has gone wrong. When the camera stream is not active (99% of the time), most of the device page is therefore taken up by a large empty black square. I was thinking it would be nice to instead display this interactive print progress view (which could be hidden when displaying the camera feed).
