I would like to request a feature that will help immensely when manually marking the center of GCPs in images. When I reset a GCP and then click ‘Try another view’, I’m having to click ‘Try another view’ many times before finding one with the correct target or having to start over because it gets stuck on the spinning wheel thinking screen. My suggestion is to replace the single image when clicking ‘Try another view’ with the entire index of images that have been uploaded for processing so I can quickly scroll through and find the appropriate images.
I would look into what is going on to make it so hard to acquire targets. Are you running a scaled coordinate system or obliques? Both of these can put the camera location far from the coordinate of the GCP and make it hard for the machine to find.
