Okay, how it took me this long to think of this after you actually released geo-alignment, I just don't know, but I would absolutely love to line up not only the pointcloud of the largest group of photos in a synth that matched, but each smaller group as well. (... several seconds later: Wait a minute, why not with the orphaned photos as well!?)
If this was done and each pointcloud in the synth were reliable, it seems like we would be on the verge of an answering the eternal "How can I correct images that didn't match the others?" question.
You tell me, guys. Good idea or bad idea?
